maths.random javascript code example

Example 1: math.random javascript

Math.random() 
// will return a number between 0 and 1, you can then time it up to get larger numbers.
//When using bigger numbers remember to use Math.floor if you want it to be a integer
Math.floor(Math.random() * 10) // Will return a integer between 0 and 9
Math.floor(Math.random() * 11) // Will return a integer between 0 and 10

// You can make functions aswell 
function randomNum(min, max) {
	return Math.floor(Math.random() * (max - min)) + min; // You can remove the Math.floor if you don't want it to be an integer
}

Example 2: js random number

var random;
var max = 8
function findRandom() {
  random = Math.floor(Math.random() * max) //Finds number between 0 - max
  console.log(random)
}
findRandom()

Example 3: javascript random

function random(min, max) {
  return ~~(Math.random() * (max - min + 1) + min);
}
random(1, 5);

Example 4: javascript randint

/* If 1 argument is given, minimum will be set to 0 and maximum to this argument
 * If 2 arguments were given, the fist would be the minimum and the second the maximum
 * The function will return an integer in [min, max[
 */
const Math.randint = function (min,max) {
  [min,max] = (max===undefined)?[0,min]:(min>max)[max,min]:[min,max];
  return Math.floor(Math.random*(max-min)+min);
}
