Generate Gaussian random numbers	snippet	math random	chess-pawns	chalarangelo	2023-04-03T05:00:00-04:00

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
