How to generate random floating point numbers in JavaScript

Answer 1

function generateRandomNumbers(n, lower, upper) {
  const random_numbers = [];
  
  for (let i = 0; i < n; i++) {
    const num = lower + (upper - lower) * Math.random();
    random_numbers.push(num);
  }
  
  return random_numbers;
}

const n = 10;
const lower = 0.0;
const upper = 3.0;

const randomNumbers = generateRandomNumbers(n, lower, upper);

randomNumbers.forEach(num => {
  process.stdout.write(`${num.toFixed(6)} `);
});
