tan atan2 vs pythag

Benchmark created by arraydifferences on

Description

tan(radian) = o/a Math.min(x2-x1,y2-y1))/sin((Math.atan2(y2-y1,x2-x1))%(Math.PI/2))

VS

Math.sqrt((x2-x1)(x2-x1)+(y2-y1)(y2-y1));

Setup

var x1 = Math.random() * 1000;
    var y1 = Math.random() * 1000;
    var x2 = Math.random() * 1000;
    var y2 = Math.random() * 1000;
    var dx = x2 - x1;
    var dy = y2 - y1;
    var halfpi = (Math.PI / 2);
