Mod operator in ios
c, ios, iphone, modulo, objective-c
Solution
You can use `fmod` (for `double`) and `fmodf` (for `float`) of math.h:
#import <math.h>
rotationAngle = fmodf(rotationAngle, 360.0f);
Problem
have been searching for a mod operator in ios, just like the `%` in c, but no luck in finding it. Tried the answer in this link but it gives the same error. I have a float variable 'rotationAngle' whose angle keeps incrementing or decrementing based on the users finger movement. Some thing like this: ``` if (startPoint.x < pt.x) { if (pt.y<936/2) rotationAngle += pt.x - startPoint.x; else rotationAngle += startPoint.x - pt.x; } rotationAngle = (rotationAngle % 360); } ``` I just need to make sure that the rotationAngle doesnot cross the +/- 360 limit. Any help any body. Thanks
