In another forum (one that's science, not software, oriented), there was a poster asking for programming advice. He's trying to port some code to a PLC, the development environment of which can't do exponentiation.
Alas, he needs to do non-integer exponents. So, my question for the Mathematical Monks is does anybody know of an exponentiation function? Because of the way exponens work, the only concern is fractional powers, i.e. those with absolute values less than one. I'm digging through my copy of Knuth and Numerical Recipes, but since real languages can do $x = $y ** $z; with some restrictions, I've never looked into that deeply into the numerical libraries.
