 Technique for Animated Number Countdown with Commas
by Randy Rubin 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;
}

Thanks! This share helped me a lot! •  Re: Technique for Animated Number Countdown with Commas by Dan Smith on Jun 27, 2012 at 4:56:09 pm 
Is there a way to do 1,000,000+ ? I need a population counter.... •  Re: Technique for Animated Number Countdown with Commas by Kolitha Bandara on Nov 24, 2015 at 5:49:44 am 
var num = effect("Slider Control")("Slider")*10
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 Commas by Ryan Paterson on 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 Commas by Arvid Eriksson on Apr 17, 2015 at 2:18:50 am 
Thank you for a simple and lean solution. Brilliant!

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 Commas by stig olsen on 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 Commas by Liran Tabib on Apr 22, 2016 at 7:12:31 am 
you can use a different approach and create the animation with the counter preset: http://www.vdodna.com/products/counterpreset/

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;
}
