javascript random number between 2 numbers 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 generate a random number between two numbers thats not 1

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

Example 3: generate random number between two numbers javascript

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 4: generate random whole number between 2 javascript

/**
 * Returns a random number between min (inclusive) and max (exclusive)
 */
function getRandomArbitrary(min, max) {
    return Math.random() * (max - min) + min;
}

/**
 * Returns a random integer between min (inclusive) and max (inclusive).
 * The value is no lower than min (or the next integer greater than min
 * if min isn't an integer) and no greater than max (or the next integer
 * lower than max if max isn't an integer).
 * Using Math.round() will give you a non-uniform distribution!
 */
function getRandomInt(min, max) {
    min = Math.ceil(min);
    max = Math.floor(max);
    return Math.floor(Math.random() * (max - min + 1)) + min;
}

Example 5: typescript random number

/**
* Gets random int
* @param min 
* @param max 
* @returns random int - min & max inclusive
*/
getRandomInt(min, max) : number{
	min = Math.ceil(min);
	max = Math.floor(max);
	return Math.floor(Math.random() * (max - min + 1)) + min; 
}
