math float32 vs number (v4)

Revision 4 of this benchmark created on

Description

Trying to multiply numbers coming from a number array or a float32 array ; and storing the result to a var, a float32array, a number array or an object

Setup

const size = 100000;
const f32 = new Float32Array(size *2); 
const nb = [];

for (let i = 0; i < size *2; ++i) nb[i] = f32[i] = Math.random();

const outf32 = new Float32Array(size);
const outNb = [];
outNb.length = size;
for (let i = 0; i < size; ++i) nb[i] = 0;

Teardown

console.log(outNb, outf32);
