math ramdom code example

Example 1: javascript get random number in range

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

//usage example: getRandomNumberBetween(20,400);

Example 2: random js

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

Example 3: nombre random js

// On renvoie un nombre aléatoire entre une valeur min (incluse) 
// et une valeur max (exclue)
function getRandomArbitrary(min, max) {
  return Math.random() * (max - min) + min;
}

Example 4: javascript random number in range

function getRandomInt(min, max) {
  min = Math.ceil(min);
  max = Math.floor(max);
  return Math.floor(Math.random() * (max - min)) + min; //The maximum is exclusive and the minimum is inclusive
}

Example 5: math.random

int random = (int) (Math.random()*(max-min+1)+min);

Example 6: randint js

/* 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 => (min,max) {
  [min,max] = (max===undefined)?[0,min]:(min>max)[max,min]:[min,max];
  return Math.floor(Math.random*(max-min)+min);
}
