Generate Gaussian random numbers

JavaScript, Math, Random · Apr 3, 2023

Generates Gaussian (normally distributed) random numbers.

Use the Box-Muller transform to generate random numbers with a Gaussian distribution.

const randomGauss = () => {
  const theta = 2 * Math.PI * Math.random();
  const rho = Math.sqrt(-2 * Math.log(1 - Math.random()));
  return (rho * Math.cos(theta)) / 10.0 + 0.5;
};

randomGauss(); // 0.5
