var range = 1000000;

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

for (let i = 0; i < n; i++) {
  a[i] = a[i] / 2;
}

 
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;
}

 
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;
}

 
for (let i = 0; i < n; i++) {  a64[i] = a64[i] / 2;}
