Function randomFloat32Array

Parameters

• n: number

  number of elements

• Optionallow: number

  lower bound (default: -1)

• Optionalhigh: number

  upper bound (default: 1)

• Optionalseed: number

  omit for genuine randomness (Math.random, the default); pass any number for a deterministic, reproducible sequence (mulberry32) — useful for regression tests that need "random-looking" data without flaking between runs

  Default range [-1, 1):

  import { randomFloat32Array } from "wgblas";
  
  const x = randomFloat32Array(4);
  console.log(x); // Float32Array [ -0.42, 0.81, -0.07, 0.55 ] (values differ each run)
  Copy

  Custom range [0, 10):

  import { randomFloat32Array } from "wgblas";
  
  const x = randomFloat32Array(4, 0, 10);
  console.log(x);
  Copy

  Seeded (deterministic):

  import { randomFloat32Array } from "wgblas";
  
  // Same seed -> identical output every run, useful for reproducible
  // regression tests that need "random-looking" data without real randomness.
  const a = randomFloat32Array(4, -1, 1, 42);
  const b = randomFloat32Array(4, -1, 1, 42);
  console.log(a);
  console.log(b);
  console.log(
    "identical:",
    a.every((v, i) => v === b[i]),
  );
