rand

Question

How is possible to improve function

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

if i want to return 'max' variable as possible?

Answer 1

just add + 1 to (max - min) so it becomes
(max - min + 1) and wrap it all with Math.floor()

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

Answer 2

i came to this solution (with user input min and max and rounded number (you can remove those))
var max = prompt("max");
var min =prompt("min");
var x = Math.floor(Math.random(min)*max);
document.write(x);

Answer 3

sorry for my misunderstanding, but did you ment you want a random number between min and max?
