Script Preparation code:
const len = 16384; window.len = len; window.arr = new Array(len); window.f32 = new Float32Array(len); window.f64 = new Float64Array(len); for (let i = 0; i < len; i++) { window.arr[i] = Math.random() * 2048; window.f32 = Math.fround(window.arr[i]); window.f64 = window.arr[i]; }
Tests:
Plain array
let a = 0; for (let i = 1; i < window.len; i++) { a = window.arr[i] * window.arr[i - 1]; }
Float32 Array
let a = 0; for (let i = 1; i < window.len; i++) { a = window.f32[i] * window.f32[i - 1]; }
Float64 Array
let a = 0; for (let i = 1; i < window.len; i++) { a = window.f64[i] * window.f64[i - 1]; }
