Benchmark: Float32 vs Float64 vs Array

Script Preparation code:

var length = 1e6;

var f32_a = Float32Array.from({length}, Math.random);
var f32_b = Float32Array.from({length}, Math.random);

var f64_a = Float64Array.from({length}, Math.random);
var f64_b = Float64Array.from({length}, Math.random);

var arr_a = Array.from({length}, Math.random);
var arr_b = Array.from({length}, Math.random);

Tests:

set f32
f32_a.set(f32_b);
set f64
f64_a.set(f64_b);
iterate and set f32
for (let i = 0; i < length; i++) { f32_a[i] = f32_b[i]; }
iterate and set f64
for (let i = 0; i < length; i++) { f64_a[i] = f64_b[i]; }
iterate and set array
for (let i = 0; i < length; i++) { arr_a[i] = arr_b[i]; }
