math.random javascript 1000 + 1 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: random number javascript

function getRandomNumberBetween(min,max){
    return Math.floor(Math.random()*(max-min+1)+min);
}
getRandomNumberBetween(50,80);

Example 3: math.random every number no range

int jj = reader.nextInt();
