angle between two angles code example
Example: javascript find smallest difference between angles
var x = Math.PI * 1.9;
var y = Math.PI * 0.1;
Math.atan2(Math.sin(x-y), Math.cos(x-y)); // -Math.PI * 0.2var x = Math.PI * 1.9;
var y = Math.PI * 0.1;
Math.atan2(Math.sin(x-y), Math.cos(x-y)); // -Math.PI * 0.2
