.random() javascript 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: generate random numbers in js

Math.floor((Math.random() * 100) + 1);
//Generate random numbers between 1 and 100
//Math.random generates [0,1)

Example 4: js random

Math.floor(Math.random() * 10) + 1 // Random number Between 1 and 10
// First Math.random give us a random number between 0 and 0,99999
// The we multiply it by 10
// And we round dow with Math.floor
// We add 1 so the result will never be 0 

// Another Example:
h.floor(Math.random() * 20) + 10 // Random number Between 10 and 20

Example 5: js math random

var n = Math.random();
n = Math.floor((n * 6) + 1); // if you want your numbers to start at 1 and end at 6 
console.log(n);
