    Hi, I came across this incredible number counter, I need help in moving the comma one place left. For example, currently, it’s like this 400,00. I want it to be 40,000.

    numDecimals = 0;

    commas = true;

    dollarSign = false;

    beginCount = 500;

    endCount = 40000;

    dur = 2;

    t = time - inPoint;

    s = ease (t, 0, dur, beginCount, endCount).toFixed(numDecimals) + "+";

    prefix = "";

    if (s[0] == "-"){

    prefix = "-";

    s = s.substr(1);

    }

    if(dollarSign) prefix += "$";

    if (commas){

    decimals = "";

    if (numDecimals > 0){

    decimals = s.substr(-(numDecimals + 1));

    s = s.substr(0,s.length - (numDecimals + 1));

    }

    outStr = s.substr(-s.length, (s.length-1)%3 +1);

    for (i = Math.floor((s.length-1)/3); i > 0; i--){

    outStr += "," + s.substr(-i*3,3);

    }

    prefix + outStr + decimals;

    }else{

    prefix + s;

    }

    Hi!

    The expression is adding a “+” to the end of the number and therefore putting the comma in the wrong spot.

    Try this line instead:

    s = ease (t, 0, dur, beginCount, endCount).toFixed(numDecimals);

    And let me know if that’s just not what you’re looking for.

    Hi Trent, thanks for your reply and direction.

    I found a better way and shorter of doing it. Leaving the code here for someone who might find it useful,

    Thanks to Nick Khoo’s video –

    Apply point control effect to the text layer and paste the below expression to sourceText param.

    s = "" + Math.round(effect("Point Control")("Point")[0]);
    "INR " + s.replace(/\B(?=(?:(\d\d)+(\d)(?!\d))+(?!\d))/g, ',') + "+";

    //use this for numbers with decimals

    s = "" + Math.round(effect("Point Control")("Point")[0]);
    "INR " + s.replace(/\B(?=(?:(\d\d)+(\d)(?!\d))+(?!\d))/g, ',') + "+";

    REGEX! Right on! This is a great look at how regex can be used in expressions!

    Also, if you have a newer version of AE (17+) and set the Expression Engine to JavaScript in the Project Settings, you can use the java function toLocaleString() to add commas/separators based on language and country.

    This would put in commas as separators:

    num = effect("Point Control")("Point")[0] ;

    num.toLocaleString('en-US') ;

    This would use spaces for French:

    num = effect("Point Control")("Point")[0] ;

    num.toLocaleString('fr-FR') ;

    You can use a slider or rotation control or even the sourceText value, but you’ll need to convert it to float or integer first:

    num = effect("Slider Control")("Slider") ;

    parseFloat(num).toLocaleString() ;

    There are also options for currency and date and more in toLocaleString(). This link has some examples: https://www.c-sharpcorner.com/article/format-number-currency-and-date-using-tolocalestring-method-in-javascript/
