math.random javascript between two numbers code example

Example 1: random int between two numbers javascript

// Between any two numbers
Math.floor(Math.random() * (max - min + 1)) + min;

// Between 0 and max
Math.floor(Math.random() * (max + 1));

// Between 1 and max
Math.floor(Math.random() * max) + 1;

Example 2: javascript random no between 2 numbers

function randomIntFromInterval(min, max) { // min and max included 
  return Math.floor(Math.random() * (max - min + 1) + min);
}

Example 3: javascript generate a random number between two numbers thats not 1

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

Example 4: 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;
}
