Putting square pegs in round holes since I have a NEW book. Hello, I have a currency field that I'm pulling in from an access database.
Any time I try and total the currency field using a matrix or table card the total shows 10 digits to the right of the decimal place instead of 2.
All the data in my source table has 1 or 2 digits to the right of the decim. Sales should be in currency format, but there is no dollar sign. That’s because all three measures in our Measure Selected calculated field have to share the same format and, by default, the format is set to automatic. We could change the format to currency, but then a dollar sign would be shown for the Quantity and Discount measures.

How can I get the format string for a currency value in analysis services. When I run an MDX query to retrieve a measure with a type of Currency, the value is returned in the expected format e.g. €,This is correct as my Cube's locale is set up to be Ireland.
Recently on a Windows Phone project I got a bug raised that I was formatting the currency for South Africa incorrectly (in particular the use of a comma to separate the Rands & cents – i.e.
the decimal mark) which sparked off an investigation into what is the correct way to format the currency in the country I live in.
tl;dr: The comma is the decimal mark for South Africa. The precision of a numeric value describes the number of digits that are used to show that value. In a scientific setting, this would be the total number of digits (sometimes called the significant figures or significant digits) or, less commonly, the number of fractional digits or decimal places (the number of digits following the decimal point).This second definition is useful in financial.
Absolutely not. Imagine trying to cope with: 4 farthings make a penny, twelve pennies make a shilling, twenty shillings to the Pound. Then there was Crown (five shillings) and the half-a-crown (you do the maths - in shillings and pence, please).

The course main objective is to provide students with a solid grasp of the probabilistic and statistical underpinnings of the most common econometric techniques. The topics studied will be of practical use to any student who plans on confronting data in their thesis or wishes to read and precisely understand the econometrics typically used in empirical research published in academic journals. Econometric theory has two parts:
The first part focuses on the specification and estimation of the linear regression models and its extensions.
The second part focuses on the theory and the applications of time series methods in econometrics.
Throughout, we will focus on both understanding and doing. The understanding will come from lectures, class discussions, and problem solving. The doing will come from extensive statistical software use. This course requires a quarter-long commitment. Econometrics is best learned by doing, and I will require you to do a fair amount of hands-on work. Hands-on work requires the use of computer software. In this class we use Julia.
Lectures of the first part of the course will be mostly based on the following two graduate textbooks:
Lectures of the second part will be based on the following textbooks:
Another reference is:
There will be two in class exam. A midterm and a comprehensive final.
The midterm will be held on March 28, 2017.
The grade will consist of a weighted average of these two exams and the problem sets. The midterm will count 30%, the problem set 30%, and the final the remaining 40%. The final grade will be the largest between the weighted grade as described above and the grade on the final. More specifically, denoting F, M, and PS your grade on the final, midterm, and problem set, respectively, your grade will be
Final Grade = max(.4*F + .3*M + .3*PS, .8*F + .2*PS, F)
Note: The midterm and the problem sets will be considered only for the first two final exam dates.
The following topics will be covered:
Asymptotic theory: law of large numbers and central limit theorems for iid and time series data
Parametric and semi-parametric estimation techniques
Properties of estimators
Conditional expectation and related concepts with application to econometrics
Single equation linear model and OLS estimation
Instrumental variables estimation of single equation linear model
Limited dependent variable models
Panel Data models
Univariate ARMA processes with stochastic and non-stochastic trends
Vector Autoregression (VAR)
Forecasting with ARMA and VAR models
Special Topics: Generalized Method of Moments
There will be a weekly problem set. The assignments will involve both theoretical and empirical work. Group study and free discussion are encouraged. But you should submit your own answers. You will probably find the class very hard to follow if you fail to spend sufficient time on all of the problem sets. The problem sets are part of the final grade as explained in the next section below.
If you have any question on the problem sets, please ask me or TA’s during our office hours. Our office hours are for you. I prefer to talk to you in person. I feel that email is not a very efficient way to ask econometric questions.
Problem set answers are to be turned in on time. You can hand in the homework AFTER the class. Late solution will not be accepted!
The TAs will lead a weekly practice session which will be held in the computer labs (301 and 306).
The sessions are an important part of the course and regular and attendance is strongly advised. During these sessions, the TA will review the concepts introduced in class and solve applied problems using Julia. Sessions are also useful for asking questions about the problem sets.
The following table gives the distribution of students across the two sessions:
Julia is a high-level, high-performance dynamic programming language for technical computing, with syntax that is familiar to users of other technical computing environments. In particular, its syntax is similar to Matlab. The similarity of the syntax means that a lot of Matlab code will run almost unmodified.
Julia has many advantages over other languages and for this reason is being extensively used in industries and in research.
Recently, the Federal Reserve of New York has open sourced its macroeconomic model (used for producing forecast about key variables and to conduct policy experiment). The code is written in Julia. You can read about it here. The code is on github.
An excellent tutorial is Programming in Julia. The tutorial is written by Thomas J. Sargent and John Stachurski. Along with being a complete textbook with Julia code for macroeconomics, this also is a very good introduction to Julia

In this section of the website we provide documents and articles which we hope will explain how we introduce and develop concepts to the children, so that families can re-inforce this at home.
Our new Y2-6 spelling scheme is called ‘No Nonsense Spelling‘. It is based on the Letters and Sounds scheme which is used in the Foundation Phase. Please find below links to some of the high frequency words which children should learn. The children have at least 3 discrete spelling lessons each week when they are taught spelling patterns and strategies to help them learn and understand these patterns. They have pink spelling journals which they bring home daily so that you can support them with the spelling pattern they are currently studying or help them to learn any set words.
We have recently purchased the ‘Accelerated Reading‘ scheme. Nearly all of the books in both classes have been scanned and colour banded according to difficulty based on the Accelerated Reading database. The children sit a STAR reading test and the results of this test determine what colour band(s) the children should be choosing books from. The test not only assesses the children’s ability to read words but also their ability to use reading skills such as inference (reading between the lines).
Your child’s colour band or number scale should be recorded inside their reading diary. When the children finish a book they will sit a quiz which will asses their understanding of the book they have just read. Each book that your child reads will earn them a number of points.
These are the 8 reading behaviours which children are introduced to
throughout Key Stage 2
Numicon is used as a maths resource throughout the Foundation Phase and KS2 at Irfon Valley.
Numicon is a multi-sensory mathematics teaching programme. When Numicon patterns are arranged in order, pupils begin to notice important connections between numbers for instance that each number is one more than the last and one fewer than the next, odd and even numbers and place value. Numicon illustrates number bonds, addition and subtraction, place value, doubling and halving, estimation, division and multiplication.
Some ideas for developing your child’s mathematical understanding at home:
Counting everyday objects at home e.g. fruit, socks, toys.
Adding one more/ less to groups of objects practically.
Talk about the position of things- on, next to, etc.
Use the language of measurement in context- heavy, light, empty, long etc.
Choose a shape of the week e.g. cylinder. Look for this shape in the environment (tins, candles etc).
Make a model using boxes/containers of different shapes and sizes. Ask your child to describe their model.
Years 1 & 2:
Number hunt- noticing numbers in our environment e.g. on doors, car number plates, telephone keypad.
Using rulers and tape measures to measure the height/length of objects in the home.
Weighing ingredients for cooking in the kitchen and doubling/halving ingredients.
Ordering days of the week/months of the year, plotting birthdays on the calendar.
Using a variety of mathematical words in everyday contexts e.g. more than, bigger, less than, take away, subtract, difference etc.
Counting in 2’s, 5’s, 10’s and 3’s.
Using numberlines to add and subtract.
Reviewing number bonds to 20 by playing ‘ping pong’. You say a number, they say the corresponding number back.
Play ‘guess my shape’. You think of a shape. Your child asks questions to try to identify it but you can only answer ‘yes’ or ‘no’ (e.g. Does it have more than 4 corners? Does it have any curved sides?)
Practise telling the time with your child.

I was thrilled to have my work selected for this show. Most of the participants are mathematicians first, and artists on the side - so their explanations for the math behind the art are quite esoteric for the rest of us. In fact, many of my mosaic abstractions are based on mathematic principals, but I only understand them from a visual perspective. In this work, 'Squaring the Circle', the central portion is geometry behind how 2 circles and a spiral form a square. The background andamento is inspired by computer images of the strokes of Jackson Pollock (now we're getting out there...!)

Is Mathematics Discovered Or Invented?
Submitted by Lance on Sun, 2008-04-27 00:56
Interesting article, and an interesting discussion at /.
"The language we use to describe mathematics is not the math itself. The math exists regardless of the symbolism used to describe it. Hence, you are incorrect. It is all discovered, but the means to describe it and put it to use is invented."
"Suppose you had a definitive, 100% guaranteed answer to the "discovered vs invented" question. What would it allow you to do that you couldn't do before? What could you predict? What would you gain?
Nothing, nothing and nothing.
It's meaningless; merely a matter of perception, wordplay and people having too much time on their hands.
Oh, and the correct answer is "discovered"."

Weiss completed his postdoctoral work at the University from 1962 to 1964.
Bourgain is the IBM von Neumann Professor at the Institute for Advanced Study, and was the sole recipient of the Breakthrough Prize in Mathematics. He was awarded the prize for “multiple transformative contributions to analysis, combinatorics, partial differential equations, high-dimensional geometry and number theory.” Bourgain received an award of $3 million.
Giombi and Pretorius, who are both University physics professors, received the New Horizons in Physics Prize, which is awarded to early-career physics researchers who have produced important results in fundamental physics. Giombi's research deals with string theory and quantum field theory, while Pretorius’ work focuses on gravitational wave physics. Giombi received an award of $50,000, and Pretorius received $100,000.
Giombi said that he is deeply honored to receive this award, and he plans to donate a portion of the money to charity. He explained that his recent results showed that certain field theories relevant to statistical mechanics and condensed matter physics may have an equivalent description in terms of certain gravitational models in higher dimensions.
"This type of correspondences often lead to non-trivial insights both on the nature of quantum gravity, and on general properties of quantum field theory," Giombi said.
Pretorius said that he is delighted and honored to receive the award, and that he plans to donate a portion of it to charity. He noted that the work that he is doing is especially exciting given the discovery of gravitational waves earlier this year, and he hopes that puzzles surrounding dark matter and Einstein's classical theory of gravity will be solved by further advancements in the field.
“I think this is only the beginning of an entirely new field of astronomy where we'll be able to ‘listen’ to many interesting phenomena in the universe that aren't observable by other means,” Pretorius said. “My advice for students interested in physics is to dive in and go for it — we're living in exciting times!”
He added that the University has offered a supportive and vibrant environment, and that the students are exceptional.
Vafa, who is the Donner Professor of Science at Harvard, received the Breakthrough Prize in Fundamental Physics, along with Joseph Polchinski of the University of California-Santa Barbara and Andrew Strominger of Harvard University. Vafa's research involves string theory, and he is currently studying the geometry of extra dimensions and the extended objects in these dimensions to understand macroscopic physics in four dimensions. Vafa received an award of $1 million, a portion of which he said would go to philanthropic causes.
“I am delighted to receive such a prize,” Vafa said. “More important than its monetary value, is the recognition of the work that my collaborators, over 150 physicists and mathematicians, and I have been involved with in the past 30 years.”
Vafa added that students should follow their true interests and not be swayed by current hot topics. He recommended that students should explore fields outside of their concentration as he met his wife at the University while taking a Persian poetry class.
Institute of Advanced Study physics professor Edward Witten GS ’76, who advised Vafa, said that he was a remarkably creative student and that it was obvious that he would go on to accomplish great things. Witten received the Breakthrough Prize in Fundamental Physics in 2012.
Vafa added that studying under Witten led to a period of exciting intellectual growth that had a dramatic impact on his thinking about physics.
Elias, who is an assistant professor in the Math Department at the University of Oregon, received the New Horizons in Mathematics Prize, which is awarded to early-career mathematicians who have produced important results in mathematics. Elias studies geometric representation theory, and for his senior thesis, he worked on a project in abstract algebra called “Minimally faithful group actions and p-groups.” Elias received an award of $100,000.
Elias said that he has a great deal of respect for the Breakthrough Prize's mission, which is improving society's culture, and was surprised and honored to receive the award.
"[The Breakthrough Foundation] wants people's heroes to be scientists, not celebrities," he said. "They want science and the pursuit of knowledge to be seen as the most exciting and glamorous activities."
University of Illinois-Chicago math professor Ramin Takloo-Bighash, who was a University professor and advised Elias on his senior thesis, said that Elias’ thesis dealt with Cayley's Theorem in elementary group theory. Takloo-Bighash said that he expected Elias to carry out explicit computations, but was surprised when Elias was able to formulate an algorithmic procedure within one week. He added that Elias’ work became the topic of a paper that he co-wrote with Elias and Lior Silberman GS '05, a professor at the University of British Columbia.
“I have followed Ben's mathematical career over the last few years and I have been continuously impressed with his work,” Takloo-Bighash said, noting that Elias published seven papers this year alone.
One of Elias’ most notable accomplishments was his proof of the 40-year-old Kazhdan-Lusztig Conjecture in 2014. Takloo-Bighash said that this was a major achievement for the field of representation theory.
“This is an extremely important area of modern mathematics which sits at the crossroads of several areas of mathematics with applications all over the place,” he said.
Thorne and Weiss received the Special Breakthrough Prize in Fundamental Physics, which was awarded in May of this year, for their work on the Laser Interferometer Gravitational-Wave Observatory, which they used to discover the existence of gravitational waves. Thorne and Weiss will share a $1 million prize with California Institute of Technology professor Ronald Drever, and the 1,012 people who worked on LIGO will split $2 million.
Weiss said that he is pleased but somewhat embarrassed to receive the award, as he noted that there are always many more people equally worthy and responsible for the work in a large collaboration. He explained that he plans to donate most of the prize money to MIT's Physics Department to fund a graduate student fellowship in experimental physics. Weiss added that he enjoyed working under Professor Robert Dicke '38 as a postdoctoral student, and recommended that students follow their passions.
"Work on those things you enjoy doing and hope that you are lucky enough to have colleagues you respect and like," he said. "This has been my experience in gravitational wave research."
Previous recipients of the Breakthrough Prize include Institute for Advanced Study professors Nima Arkani-Hamed, Juan Maldacena GS ’96, Nathan Seiberg, Richard Taylor GS ’88, and Witten, along with University professors B. Andrei Bernevig, Alexander Polyakov, and David Botstein. Nobel laureate Arthur McDonald, who received the Breakthrough Prize last year, completed his postdoctoral work at the University. Alumni who have won the award include Eric Lander ’78, the Director of the Broad Institute at MIT, and Terence Tao GS ’96, a professor of mathematics at UCLA.


Predictive Moving Average Indicator For Tradestation
Go into the settings, and adjust how many periods the indicator should calculate, such as 15, 50, or 100. The derivation and properties of the simple central moving average are given in full at Savitzky–Golay filter. We can then use the standard score to normalize data with respect to the moving average and variance. This algorithm is based on Welford’s algorithm for computing the variance. and the average calculation is performed as a cumulative moving average. Given a series of numbers and a fixed subset size, the first element of the moving average is obtained by taking the average of the initial fixed subset of the number series.
Rather, it is designed to keep you in line with the security’s price trend by buying shortly after the security’s price bottoms and selling shortly after it tops. If you feel that you need to try and capture more of your gains, while realizing you may be shaken out of perfectly good trades- the exponential moving average will suit you better. The exponential moving average, however, adjusts as it moves to a greater degree based on the price action. To learn more about the exponential moving average and its calculations, please visit the article – ‘Why Professional Traders Prefer Using the Exponential Moving Average‘.
Most investors will look for a cross above or below this average to represent if the stock is in a bullish or bearish trend. A Rolling Moving Average is an additional type of Moving Average. In a Simple Moving Average, the price data have an equal weight in the computation of the average. Also, the oldest price data are removed from the Moving Average when a new price is added to the computation. If the chart displays daily data, then period denotes days; in weekly charts, the period will stand for weeks, and so on. For example, when the price is in an overall upward trend, the SMMA indicator will remain below it.
Moving Average Types
Are you able to guess which line is the exponential moving average? You can tell because even though the SMA and EMA are set to 10, the red line hugs the price action a little tighter as it makes its way up. I was using TradeStation at the time trading US equities, and I began to Retail foreign exchange trading run combinations of every time period you can imagine. Once I landed on trading volatile stocks, they either gave false entry signals or did not trend all day. So, after reviewing my trades, I, of course, came to the realization that one moving average is not enough on the chart.
Exponential – An exponential moving average with a greater weight for recent prices. An N-period Moving Average indicator EMA takes more than N data points into account and gradually dilutes past data’s effect.
To truly appreciate the value of moving averages, we need to see them work in various contexts. At this point, the market fell, but the MA continues to point up. Assuming that the bull trend will persist, this divergence offered a long pullback trade.
Moving averages are one of the core indicators in technical analysis, and there are a variety of different versions. The average is called “moving” because it is plotted on the chart bar by bar, forming a line that moves along the chart as the average value changes. In most trading platforms, you can choose between different moving average indicators, including a simple or an exponential moving average. You can also choose the length of time for the moving average. A commonly used setting is to apply a 50-day exponential moving average and a 200-day exponential moving average to a price chart (see Moving averages applied to the S&P 500 chart). The other type of moving average is the exponential moving average , which gives more weight to the most recent price points to make it more responsive to recent data points.
Exponentially Weighted Moving Variance And Standard Deviation
You can use the same signals with two Moving Averages, but most market technicians suggest using longer term averages when trading only two Rolling Moving Averages in a crossover system. Like all types of moving averages, there is no recommended periods to use when using this type of moving average. It is up to each trader to work eur and find the periods that work well for them. There are several types of moving averages like simple, exponential, and weighted. In this article, we will look at the Smoothed Moving Average and some of the strategies you can use to trade it. We will not go through boring formulas and spreadsheets of moving average calculations.
The picture shows dynamics of the capital when this strategy is applied in the BTC/USD market with the hourly time-frame. As you can see, more than 700 trades were executed and the profit factor was around 1. In practice, it would have been a loss due to commission fees and slippages. Additional filters could be added to such a trading system – for example, to open trades only if the price closes above or below both averages after their intersection.
Understanding The Otc Market Tiers
This reiterates that consistently making money trading stocks is not easy. Day Trading is a high risk activity and can result in the loss of your entire investment. EMA gives more weight to current data of a trading period, while SMA calculates the average price data of the entire period.
- The price will not always respect the moving average in this way.
- In fact, Moving Averages form the basis of several other well-known technical analysis tools such as the Bollinger Bands and the MACD.
- In fact, the 200-day moving average may offer support or resistance simply because it is so widely used.
- There have been several crossovers by the 50-day and 200-day moving averages over the past several years, and trading these signals may not have aligned with your objectives.
- The simple moving average is extremely popular with traders, but like all technical indicators, it has its drawbacks.
- If you feel that you need to try and capture more of your gains, while realizing you may be shaken out of perfectly good trades- the exponential moving average will suit you better.
You may additionally specify open, high, low, close, midpoint, or average price to be used in the computation of the Rolling Moving Average in the Input Field. A stock’s share structure can have a big impact on how a stock trades. Learn how you can analyze share Foreign exchange reserves structures and use this analysis to improve your trading.

The result is the average price of the security over the time period. In calculating the the current day’s exponential moving average, the exponential moving averages of all the previous days in the moving average window are required. In general, a simple moving average is used for the oldest data point in the calculation window since the exponential moving average requires an external reference point to start. In reality, to reduce calculation time, most software uses at least 250 intervals and can be accurate to within a fraction of a cent. The moving Average is a common indicator that traders use to determine trends in the market. Moving averages are often used to determine market entries as well as support and resistance levels. Just as it is with most technical analysis tools, moving averages should not be used on their own.
Moving Average And Other Technical Indicators
These TradeStation indicators come with a 30 day money back guarantee. During the first 30 days after purchasing these indicators you can use and evaluate these indicators as much as you like. If after purchasing these indicators you decide they are not right for you just let us know within 30 days for a full refund. Price Target – displays the price required for the two moving average to meet. Xover Bars – displays the number of bars since price last crossed the moving average. Crossed – alerts that price has crossed the moving average on this bar by displaying a text message in the column. Exponential moving averages achieve the benefits of weighting combined with ease of construction.
At times a stock will crack right through the average, but I don’t panic that a sell-off is looming. It all comes down to my ability to size up how a stock is trading in and around the average. I would try one system one day and then abandon it for the next hot system. This process went on for years as I kept searching for what would work consistently regardless of the market. The point is, I felt that using the averages as a predictive tool would further increase the accuracy of my signals. This way I could jump into a trade before the breakout or exit a winner right before it fell off the cliff.
Popular Simple Moving Averages
In these instances, the MA acted as effective support for the market. A steep line results from persistent action on one side of the MA. Finally, a substantial bear gap coupled with a change in the MA slope highlighted a bearish reversal. When the price structure aligns with the MA, the market is trending. Experiment with different look-back periods to see which works best for you. Higher settings tend to work well for observing trends, and lower lookback periods are good for timing.

By The Frequency Project
The Universal Language of Mathematics and Frequency 🎶
Throughout the vast tapestry of history and the evolution of human understanding, there has always been a consistent thread: the universe communicates in a language that transcends mere words. This language, deeply embedded in the rhythms of mathematics, the elegance of geometry, and the resonance of frequency, might be the very key to unlocking the mysteries of the cosmos. It’s a language that doesn’t rely on alphabets or scripts but on patterns and vibrations. If there’s a universal language that binds every atom, star, and galaxy, it’s expressed through these elements. This intricate dance of numbers and patterns has been the subject of contemplation and reverence for ancient civilizations, mystics, and scholars alike.
The Magic of Number 60 and Ancient Civilizations 🏛
The number 60 isn’t just a mere numeral; it’s a symbol of ancient wisdom and cosmic understanding. Civilizations, from the riverbanks of Mesopotamia to the astronomical observatories of Mesoamerica, have held a deep fascination with this number. The ancient Sumerians, often hailed as the cradle of civilization, developed a unique counting system rooted in the number 60. This system, which intricately divides time into seconds, minutes, and hours, is a testament to their advanced mathematical prowess. But what’s even more intriguing is the origin of this knowledge. Ancient texts and inscriptions hint at the Sumerians’ belief that they were bestowed with this knowledge by celestial beings known as the Anunnaki. These sky-god visitors, whether mythological or real, have left an indelible mark on human civilization, shaping our understanding of time and mathematics.
Pythagoras and the Musical Universe 🎵
The name Pythagoras often evokes memories of triangles and theorems in our minds. However, this ancient Greek polymath’s contributions extend far beyond geometry. Pythagoras ventured into the realms where mathematics, music, and spirituality converge. He discovered that when strings of varying lengths were plucked, they produced distinct tones, each resonating with a unique mathematical frequency. This revelation led to the creation of a musical scale that, to this day, forms the foundation of most modern music. But there’s more to this scale than meets the ear. The video delves deep into the significance of the number 432 in Pythagorean tuning. This number, often revered in ancient cultures, resonates with the very geometry and frequency of existence, offering a harmonious soundtrack to the dance of the cosmos.
Geometry, Tones, and the Cosmos 🌌
The universe, in all its vastness, is a symphony of shapes and sounds. Every geometric shape, from the simplest triangle to the most complex polyhedron, sings a unique song. The video introduces a captivating experiment that explores the tones produced by different geometric shapes. It suggests that geometry isn’t just a visual experience; it’s an auditory one. Shapes like the Platonic solids, discovered by Plato, aren’t just theoretical constructs; they represent the fundamental building blocks of nature, resonating with unique frequencies that echo through the fabric of reality.
The Cosmic Significance of 432 🔍
Numbers, in their essence, are more than just mathematical symbols; they are keys to cosmic doors. The number 432, in particular, holds a special place in the annals of ancient wisdom. Revered by various cultures, mystics, and scholars, 432 is seen as a cosmic key that unlocks deeper layers of understanding. Along with other numbers like 144,000 (a number with deep esoteric significance), 432 hints at a grand pattern based on frequency mathematics, time, space, and geometry. This synchronistic dance of numbers and patterns might be the building blocks of a language that could bridge our understanding of the microcosm and the macrocosm.
In Conclusion 🌍
As we journey through the corridors of knowledge and understanding, we realize that the universe has always been in conversation with us. Through energy, frequency, and form, it shares its secrets, waiting for us to listen and understand. The insights from this exploration, inspired by the revelations from a video titled “Sonic Geometry: The Language of Frequency and Form,” serve as a testament to the timeless dance of sound and geometry.


As we know, C# has introduced the concept of infinity for some time. Both double and float types have the PositiveInfinity and NagativeInfinity constants in recent C# versions and some other properties are provided as well such as IsPositiveInfinity and IsNagativeInfinity to help check the double and float values.
double aaa = double.PositiveInfinity;
double bbb = double.NegativeInfinity;
float aaaa = float.PositiveInfinity;
float bbbb = float.NegativeInfinity;
Moreover, the PositiveInfinity and NagativeInfinity will all take part into real calculations. That looks nice, but will only cause troubles based on our experiences.
The biggest problem we think is that the infinity concept only applies to the double and float values. For other types such as integer and decimal, they cannot hold infinity either positive or negative in the C# language so far.
When a good integer is trying to be divided by a zero constant, the C# editor would warn us with the tiny red wave lines under the expression with a tooltip along (Error: Division by constant zero), and the Visual Studio compiler will not let it go through.
If the zero is assigned to an integer variable and then the variable is used to divide an integer constant, both the C# editor and compiler would be happy. However, when the code is being executed, a DivideByZeroException with an explanation like ‘Attempted to divide by zero’ would occur at run time.
All these inconsistencies seem not a big deal in case we don’t mix using them together. Otherwise, serious problems would come along. For example, if the following code is run,
double a = 5.5;
double b = 0;
int c = (int)(Math.PI * 2 * a / b);
double d = Math.PI * 2 / c;
int i = (int)Math.Floor(180.0 / d);
a result out of most people’s imaginations we believe would be generated:
Let’s put aside the real value. Please pay attention to the sign. It is NEGATIVE!
If no conversions between integer and double values at all, i.e. values are all in doubles, the output will be, ‘as expected’, Infinity.
Readers make the judgement.
Overall, all these inconsistencies only cause trouble for people like us. If the infinity concept is not brought into C# at all such that exceptions would be thrown out in all cases including double/float and integer/decimal types as in old versions, people may not be so annoyed.
Ask a simple question: why cannot an integer be infinity if a double value can?
Haven’t we all seen something like this everywhere in math books?
If the integer infinity is not more important than the double infinity, should not they be equal at least? In fact, what’s the difference between integer infinity and double infinity by the way?
Some may argue that an integer in the computer world cannot hold infinity. Then can double type really do in the current 64-bit cyber world or maybe even 1024-bit one in the future?


If you have children or grandchildren at school you have most likely heard of EQAO testing.
The EQAO (Education Quality and Accountability Office) is an independent agency that creates and administers large-scale assessments to measure Ontario students’ achievement in reading, writing and math at key stages of their education. The tests are written in the following grades:
- Grade 3, Primary Division (reading, writing and math)
- Grade 6, Junior Division (reading, writing and math)
- Grade 9 Math
- Grade 10, Ontario Secondary School Literacy Test (OSSLT)
Data from EQAO is a key component in helping school board’s see the larger picture, which includes report card data, classroom assessments, along with teacher and student perceptual data. These findings are collectively used to tell us how we’re doing at the Board, school and classroom level.
Today, the Provincial and local EQAO results for all key assessment stages have been released and Avon Maitland’s staff have begun analyzing the data.
Avon Maitland Results At-a-Glance:
Grade 3 (Primary) and Grade 6 (Junior)
The Assessment of Reading, Writing and Mathematics focuses on the skills that students are expected to have learned by the end of Grade 3 and Grade 6. Students write this test during a two-week testing window in May/June each year.
The Avon Maitland District School Board continues to keep pace with provincial gains in literacy in both the Primary and Junior Assessments of Reading and Writing (EQAO). Over the past five years, the AMDSB scores in Junior (Grade 6) Reading have steadily improved. Our Primary students continued on their upward trajectory in Reading, with 70% of our students meeting or exceeding the provincial standard in Reading, a 5-point gain over the previous test score. Writing scores dipped slightly, with 70% of students meeting or exceeding the provincial standard.
Avon Maitland’s Elementary Schools Keeping Pace with Provincial Growth in Literacy
Avon Maitland’s achievement in Mathematics in both the Primary and Junior Divisions mirror the provincial trend. Primary Mathematics has increased slightly to 65%, up 2 percentage points from the previous testing year, while junior scores declined 3 points to 46%. Primary and Junior Mathematics, both provincially and locally, are now a higher priority in improvement planning at the provincial, board and school levels.
Grade 9 Math
The Grade 9 Assessments of Mathematics tests the math skills students are expected to have learned by the end of Grade 9. Different versions of the test are administered in the academic and the applied math courses. Students in first-semester math courses take the test during a two-week testing window in January; students in second-semester or full-year math courses take the test during a two-week testing window in June.
Provincial results are as follows: 45% of students in the applied math course met the provincial standard, a drop of 2 percentage points from 2015; and 83% of students in the academic math course met the provincial standard, a drop of 2 percentage points from 2015.
Avon Maitland District School Board applied and academic scores followed this trend as well. Of the students taking applied mathematics, 48% successfully met the provincial standard. Of the students taking academic mathematics, 82% successfully met the provincial standard. The five-year trend data is as follows:
Applied 3 year rolling average
2011-2014 – 55%
2012-2015 – 56%
2013-2016 – 55%
Academic 3 year rolling average
2011-2014 – 87%
2012-2015 – 87%
2013-2016 – 85%
Grade 10, Ontario Secondary School Literacy Test (OSSLT)
The OSSLT is a provincial test that measures whether or not students are meeting the minimum standard for literacy across all subjects up to the end of Grade 9. Successful completion of the literacy test is one of the requirements to earn an Ontario Secondary School Diploma.
74% of Avon Maitland students were successful in this latest round of OSSLT
Used in conjunction with other data sources (e.g., report card data, classroom assessments, teacher and student perceptual data, etc.), data from the OSSLT is a key component in seeing the ‘big picture’ of how our system, our schools and our students are doing.
“In response to our OSSLT results, there will be a renewed emphasis on literacy achievement in our secondary schools,” says Superintendent of Program Jane Morris. “Schools will be developing literacy plans that identify areas of weakness and needs and set a course in support of individuals and student sub-groups.”
Historically, students across the province write the OSSLT on the same date, usually in late March each year. This year, however, students have the additional option of taking the OSSLT in an online environment on October 20.
”We are excited that our students will be given this additional opportunity to demonstrate their language skills this year,” says director Ted Doherty. “The ability to complete the test online will be a welcome change for many of our students as well.”
Annually the review of EQAO data by Avon Maitland staff ultimately results in adjustments to the Board’s improvement plan, sheds light on individual student needs and steers the course for staff meetings and professional development days as schools further refine student achievement plans.
The review process on a Board level has begun and will continue in depth alongside school leaders on the PD day this Friday (September 23, 2016).
For a more in depth look at the EQAO results please visit the Education Quality and Accountability Office (EQAO) website.
