The only thing I do not like about it is the math functionality is quiet limited.

You would have to nest functions to get proper order of operations. Using function names instead of actual symbols. Seems like it would be easier to do something like math(a+b/2) and have it know that whatever was inside that function is math to be parsed.

I might be nitpicking.
