Script Preparation code:

var n = 10000;
var range = 1000000;

var a = [...Array(n)].map(_ => Math.random(range));
var a32 = new Float32Array(a);
var a64 = new Float64Array(a);

Tests:

Array
for (let i = 0; i < n; i++) { a[i] = a[i] / 2; }
Float32Array
for (let i = 0; i < n; i++) { a32[i] = a32[i] / 2; }
Float64Array
for (let i = 0; i < n; i++) { a64[i] = a64[i] / 2; }
