Round number up to the nearest multiple of 3

I need a javascript call that will round numbers up to the nearest multiple of 12.

Some examples:

1 -> 12

7 -> 12

14 -> 24

27 -> 36

Does anyone know of a good method for doing this? All I can think of is “If between 1-11, make it 12. If between 13-23, make it 24, etc.” But that doesn’t seem very efficient.

Answer 1

Use Math.ceil()

var n = 13;
var next = Math.ceil(n/12) * 12;
