How to format a float to two digit

Question

I am using this code to get float with only two number after the . :

var number = 1.9090909090909092;
var newNumber = (number).toFixed(2);

And in newNumber i get : 1.91 instead of 1.90. Any idea why it happen?

Because it is correct. It is not slicing the later digits. Rather it is rounding off to 2 digits. — Sameer Sawla, Mar 13 '15 at 19:27
@SameerSawla there is any method that can round the digit down? — YosiFZ, Mar 13 '15 at 19:31
I was to give the solution as cpolito gave. You could do that way. — Sameer Sawla, Mar 13 '15 at 19:35

if you want to format a float to any number of digits use this function:

function truncate(num, pos) {

    return Math.floor(num*Math.pow(10, pos))/Math.pow(10, pos);

}

where num is the float and pos is the number of digits you want after the decimal.
