Javascript always round up to X decimal places

I need to write a function that will ALWAYS round up, but will either round up to 0, 1 or 2 decimal places, depending on if the function is passed a 0, 1 or 2.

Examples...

Round to 0 decimal places:
13.4178 = 14

Round to 1 decimal place:
13.4178 = 13.5

Round to 2 decimal places:

13.4178 = 13.42

I've found Math.ceil but this only rounds up to a whole integer and to fixed() will round up or down, not just up. Is there a way to round up in the way I've described above?

Answer

You could use a factor for multiplication with ten and the power of the wanted decimal count and then round it and adjust the dot.

function up(v, n) {
    return Math.ceil(v * Math.pow(10, n)) / Math.pow(10, n);

}

console.log(up(13.4178, 0));
console.log(up(13.4178, 1));
console.log(up(13.4178, 2));
