WebIf your two angles are x and y, then one of the angles between them is abs (x - y). The other angle is (2 * PI) - abs (x - y). So the value of the smallest of the 2 angles is: min ( (2 * PI) - abs (x - y), abs (x - y)) This gives you the absolute value of the angle, and it assumes the inputs are normalized (ie: within the range [0, 2π) ).
