random equation generator library for js code example

Example 1: js random int

function getRandomInt(min, max) {
    min = Math.ceil(min);
    max = Math.floor(max);
    return Math.floor(Math.random() * (max - min + 1)) + min;
}

Example 2: javascript pseudo random

var seed = 0;
var modulus = 2 ** 32;
var a = 1664525;
var c = 1013904223;

function getRandom() {
  var returnVal = seed / modulus;
  seed = (a * seed + c) % modulus;
  return returnVal;
}
