Added the ability to parse `sqrt`,` pow`

Not sure what Pseudo a good name, but I couldn't think of anything better :)

Update Tests.fs - now the test will not fall when running on systems where decimal point is written in another way (for example, a comma).

@cdrnet any comments?

Thanks for looking into this!

It should work for now this way, but I think we need a solution for things like this outside of the parser/format logic in the long term.
