Distance between two points:
sqrt((x1-x2)^2 + (y1-y2)^2)
Is there a way to do this math faster in objective-C ?
EDIT: I think I need to clarify above. I wrote the formula above just to clarify what formula I am using to calculate the distance. ^ is not meant to represent xor - I just wanted to represent the mathematical formula without using any functions like pow or anything, so I meant to use ^ to "raise to the power off". I was wondering if anyone knows if using bitwise operators, or otherwise writing code in assembly would give an optimized version. I am using the formula in an iPhone / iPad application.
