math float32 vs number

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 = 10000;
const f32 = new Float32Array(size); 
const nb = [];


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

Test runner

Ready to run.
