    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;
    }

    Is there a way to do 1,000,000+ ? I need a population counter….

    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.

    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)

    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!

    Hi,

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

    Best, Stig
