how to use math.random in js 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: javascript get random number
// Returns a number between min and max
function getRandomArbitrary(min, max) {
return Math.random() * (max - min) + min;
}
Example 4: angular random number between 1 and 10
function randomNumber(min, max) {
return Math.random() * (max - min) + min;
}
