Is there an easy way to convert an angle (in degrees) to be between -179 and 180? I'm sure I could use mod (%) and some if statements, but it gets ugly:


//Make angle between 0 and 360
angle%=360;

//Make angle between -179 and 180
if (angle>180) angle-=360;

It just seems like there should be a simple math operation that will do both statements at the same time. I may just have to create a static method for the conversion for now.
