Script Preparation code:
var N = 1000000; var x = new Float32Array(N); var y = new Float32Array(N); var theta = new Float32Array(N); for (var i = 0; i < N; ++i) { x[i] = 100* Math.random(); y[i] = 100* Math.random(); } for (var i = 0; i < N; ++i) { theta[i] = 2 * Math.PI * Math.random(); }
Tests:
sin
var fn = Math.sin; for (var i = 0; i < N; ++i) { fn(theta[i]); }
cos
var fn = Math.cos; for (var i = 0; i < N; ++i) { fn(theta[i]); }
tan
var fn = Math.tan; for (var i = 0; i < N; ++i) { fn(theta[i]); }
asin
var fn = Math.asin; for (var i = 0; i < N; ++i) { fn(x[i]); }
acos
var fn = Math.acos; for (var i = 0; i < N; ++i) { fn(x[i]); }
atan
var fn = Math.atan; for (var i = 0; i < N; ++i) { fn(x[i]); }
atan2
var fn = Math.atan; for (var i = 0; i < N; ++i) { fn(x[i], y[i]); }
