Between -180 and 180 degrees (convert a larger angle)

  • #1

I need a formula to put an angle between -180 and 180 and recycle if not in the range.

I can do it between 0 and 360:

angle = deg - 360 * floor(deg / 360)

just not between -180 and 180

Oh and what is the name of this function?

Take what you have and subtract 180.

Unless I'm not understanding what you're asking.

Function is modulo (mod). What you are asking for is mod 360.

EDIT Just add ## \pi ## to your formula and you will hit an angle in that interval. The interval [-180,180] is the translation of [0,360] by ##- \pi ##
