# Technique for Animated Number Countdown with Commas

FAQ   •   VIEW ALL Technique for Animated Number Countdown with Commas on Feb 9, 2012 at 12:04:14 am

Hi All,

Ran into this issue and combined like two techniques to get a really easy solution - thought I'd share it.

To get a number to countdown (from say 256,000 to 152,000 with commas, no decimal) follow these steps. (I didn't write most of the expression, got it from a website)

1. Create an empty text layer.

2. Go to Effects -> Expression Controls -> Slider Control

3. Twirl Down the Text Layer and 'alt (option on mac) + click' Text Source to open expression editor.

4. Enter the expression below.

5. Use the slider control effect to animate number. Enter the actual value instead of using the slider for numbers larger than one hundred. Simply key frame the effect and use the character editor to format the text. (Goes as high as 1,000,000)

Expression:

var num = effect("Slider Control")("Slider")
num = Comma(num);
[num]

function Comma(number)
{
number = '' + Math.round(number);
if (number.length > 3)
{
var mod = number.length % 3;
var output = (mod > 0 ? (number.substring(0,mod)) : '');
for (i=0 ; i < Math.floor(number.length / 3); i++)
{
if ((mod == 0) && (i == 0))
output += number.substring(mod+ 3 * i, mod + 3 * i + 3);
else
output+= ',' + number.substring(mod + 3 * i, mod + 3 * i + 3);
}
return (output);
}
else return number;

Very nice, saved to useful expressions folder.

New response to old post, this helped me a lot with a project I am working on. However, I used point control instead of slider to overcome the arbitrary 1,000,000 limit.

The expression was (including commas):

var num = effect("Point Control")("Point")

num = Comma(num);
[num]

function Comma(number)
{
number = '' + Math.round(number);
if (number.length > 3)
{
var mod = number.length % 3;
var output = (mod > 0 ? (number.substring(0,mod)) : '');
for (i=0 ; i < Math.floor(number.length / 3); i++)
{
if ((mod == 0) && (i == 0))
output += number.substring(mod+ 3 * i, mod + 3 * i + 3);
else
output+= ',' + number.substring(mod + 3 * i, mod + 3 * i + 3);
}
return (output);
}
else return number;

Hi David,

This expression is extremely helpful for what I need in my project. I just had 1 question, how do I go about including a £ or \$ symbol at the beginning of the number as it counts up?

Thanks Re: Technique for Animated Number Countdown with Commason Jun 20, 2017 at 6:22:32 pm

Hi Jameel,

You can add it to the num variable like so:

var num = effect("Point Control")("Point")

num = "\$" + Comma(num);
[num]

function Comma(number)
{
number = '' + Math.round(number);
if (number.length > 3)
{
var mod = number.length % 3;
var output = (mod > 0 ? (number.substring(0,mod)) : '');
for (i=0 ; i < Math.floor(number.length / 3); i++)
{
if ((mod == 0) && (i == 0))
output += number.substring(mod+ 3 * i, mod + 3 * i + 3);
else
output+= ',' + number.substring(mod + 3 * i, mod + 3 * i + 3);
}
return (output);
}
else return number;

my problem is the same as someone else posted; need to show a population countup from 0 or 100,000 to over 1 billion or over. Re: Technique for Animated Number Countdown with Commason Jul 15, 2013 at 9:30:24 pm

This is probably too late but I just saw this post now, to go over a million, just multiply the slider value in the first line of the expression like so-

var num = effect("Slider Control")("Slider") * 100 (or whatever number you want) Re: Technique for Animated Number Countdown with Commason Apr 30, 2014 at 6:02:02 pm

This is very useful, thanks for sharing!
In Italy we use commas instead of dots, so I would need to place the comma only before the last (or last two) digit.
I tried this way

var num = effect("Slider Control")("Slider")
num = Comma(num);
[num]

function Comma(number)
{
number = '' + Math.round(number);
if (number.length > 2)
{
var mod = number.length % 1;
var output = (mod > 0 ? (number.substring(0,mod)) : '');
for (i=0 ; i < Math.floor(number.length / 1); i++)
{
if ((mod == 0) & (i == 0))
output += number.substring(mod+ 1 * i, mod + 1 * i + 1);
else
output+= ',' + number.substring(mod + 1 * i, mod + 1 * i + 1);
}
return (output);
}
else return number;
}

but I get a comma after every digit.
Any idea?
Thank you! Re: Technique for Animated Number Countdown with Commason Sep 28, 2015 at 11:04:45 am

Hi,

This expression actually adds a least 10 numbers behind the comma. How to avoid that?

Best, Stig Re: Technique for Animated Number Countdown with Commason Nov 26, 2015 at 12:07:03 pm

And if you would like to count over 1,000,000 and keep the comma's in:

startCount = 0;
endCount = 48000000;
countDur = 3;

var num = Math.round(linear(time,0,countDur,startCount,endCount))
num = Comma(num);
[num]

function Comma(number)
{
number = '' + Math.round(number);
if (number.length > 3)
{
var mod = number.length % 3;
var output = (mod > 0 ? (number.substring(0,mod)) : '');
for (i=0 ; i < Math.floor(number.length / 3); i++)
{
if ((mod == 0) && (i == 0))
output += number.substring(mod+ 3 * i, mod + 3 * i + 3);
else
output+= ',' + number.substring(mod + 3 * i, mod + 3 * i + 3);
}
return (output);
}
else return number;

Hi, for some reason this code (or any other similar to this one) doesn't work with Adobe After Effects CC 2019. Do you have any idea why is that? Thank you Re: Technique for Animated Number Countdown with Commason Mar 8, 2019 at 11:46:21 am

In CC2019 first go to: File • Project Settings • Expressions ; set it to Legacy ExtendScript﻿ Re: Technique for Animated Number Countdown with Commason Jun 21, 2019 at 7:29:13 am
