Fractional exponents in C?	by toysbfun	2009-05-08 18:36:30
I'm trying to take the square root of 2 here, but I keep getting an "expected expression before ‘float’" error. If this is possible, what am I doing wrong? `float a, b, c; int main(void) { a = 2.0; b = (1.0/2.0); c = float pow(float a, float b); }` Side note: yes, I know there's `sqrt()`, but a) that doesn't help if I later need, say, the seventh root and b) I'm having trouble with that too. Side question: can Java do fractional exponents? I plan on re-writing this in Java if I get OpenJDK working.
