Counter-Up - counting starting from two zeros

Question

Currently I'm using Counter-Up jQuery plugin and I have a question. How to modify this code to get counting starting from 00, not from 0? I want to obtain a list like: 00, 01, 02 ... 10, 11, 12 etc. not 0, 1, 2 ... 10, 11, 12 etc.

00 can only be represented in javascript by using a string - rethink what you want ... you can count numbers, but you can display them how you want — Jaromanda X, Sep 02 '15 at 10:58
Okay, so how to display this additional zero when current state is less than 10?' — JaKoZo, Sep 02 '15 at 11:00
Something like `if ((num).toString().length === 1) num = '0' + num;` — Andy, Sep 02 '15 at 11:02

In jquery.counterup.js file, line 62

Replace:

 $this.text($this.data('counterup-nums').shift());

With:

 $this.text(padZeros($this.data('counterup-nums').shift(),$settings.padLength||5));

Add padZero function on your app:

function padZeros(str, len){
    return Array(len-String(str).length+1).join('0')+str;
}

Usage:

$('.counter').counterUp({
    delay: 10,
    time: 2000,
    padLength: $('.counter').text().length
});

You have to modify jquery.counter.js file as below (commented with " /* Added */ ")
