random number in range js 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 get random number in range

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

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

Example 3: javascript get random floating number

const randomFloat = (min, max) => Math.random() * (max - min) + min;

Example 4: random in a range js

const rnd = (min,max) => { return Math.floor(Math.random() * (max - min + 1) + min) };

Example 5: Generate random whole numbers within a range javascript

function randomRange(min, max) {

	return Math.floor(Math.random() * (max - min + 1)) + min;

}

console.log(randomRange(1,9));

Example 6: random number in range js

var min = 10, max = 25;
//inclusive random (can output 25)
var random = Math.round(Math.random() * (max - min) + min);
//exclusive random (max number that can be output is 24, in this case)
var random = Math.floor(Math.random() * (max - min) + min);
//floor takes the number beneath the generated random and round takes
//which ever is the closest to the decimal
