JavaScript - random int in range
4 points
Hi, today I would like to show you how to generate random integer number in the given range in JavaScript.
xxxxxxxxxx1
/*2
inclusive min (result can be equal to min value)3
inclusive max (result can be equal to max value)4
*/5
function randomizeInteger(min, max) {6
return min + Math.floor((max - min + 1) * Math.random());7
}8
9
// Example:10
console.log(randomizeInteger(0, 2)); // 011
console.log(randomizeInteger(0, 2)); // 212
console.log(randomizeInteger(0, 2)); // 113
console.log(randomizeInteger(0, 2)); // 1If we want to change the range, we just need to call this method with our desired min and max.
About min and max value as stated in a comment:
- inclusive min (result can be equal to min value)
- inclusive max (result can be equal to min value)
