Benchmark: Trig functions plusplus

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]); }
division
for (var i = 0; i < N; ++i) { i/5 }
