Does anyone know of a mathematical expression handler, in
the spirit of for example regex(3) for regular expression.

What I would like the thing to do is for example take a
string:

		"tanh(0.3)+2.0*sin(3.2)-3.0"

and return its value, and be reasonably fast.  I`m sure there
must be something like that lurking somewhere, so I could spare
me the yacc hacking.

		Thanks,

				Kjartan
