I was experimenting around a little with making my own square root functions and testing them. Of course I didn't want to spend time on making the fast so this is what they looked like:

inline float sqrf(float a) {return pow(10, log(a)/2);} inline float sqr3(float a) {return pow(a, 0.5);}

the times I got when testing them were something like this for 10000 calculations: sqrt (no mine): 0.004 sqrf: 0.02 sqr3: 0.01
