In C it was

#include <math.h>
double sqrt(double num);

where the square root is returned. If num is negative, an error occurs. This should still be valid in C++.

1st of all, congrats on Genetic! https://www.sharkyforums.com/images/.../2005/06/5.gif

driver's suggestion would work. Another option is also in math.h

double pow( double x, double y );

Just raise x to .5 and you'd get the same thing. This might be a good command to know if you need to raise things to powers.

But the real question is, which one is fast? https://www.sharkyforums.com/images/.../2005/06/5.gif
