Temperature converter ex: negative values
Just tested some examples for the first time today.
There is a funny thing about the temperature converter : it accepts mathematical expressions (-,+,*,/ but probably not ^ unless imported with std/math).

Yet, it does not accept any negative number in the celsius field at least.
But it converts without problem if 0.0-1.0 is given.

As a side not too, "1.0/" in the Celsius Field gives "inf" in the Farenheit field while I suppose it should tell it is an invalid value instead.

These are not really bug/limitations of the owlkettle library, but of the demo itself.
Feel free to close this "issue", since I guess bugs in the library are more important than bugs in the demos.
