js random number code example
Example 1: how to generate a random number in javascript
//To genereate a number between 0-1
Math.random();
//To generate a number that is a whole number rounded down
Math.floor(Math.random())
/*To generate a number that is a whole number rounded down between
1 and 10 */
Math.floor(Math.random() * 10) + 1 //the + 1 makes it so its not 0.
Example 2: 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 3: 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 4: random number generator javascript
Math.floor(Math.random() * (max - min + 1)) + min;
//max is the highest number you want it to get
//min is the lowest number you want it to get
Example 5: 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 6: generate random numbers in js
Math.floor((Math.random() * 100) + 1);
//Generate random numbers between 1 and 100
//Math.random generates [0,1)
