Question

Adding comma to Numbers in Expression Counter

Hi All,

 

I'm new to expression controls in after effects. I have a number counter and I've tried a few different approaches to this (Slider control and a longer string of expression code). Ultimately I decided to use this simple control as it allowed me to control how the numbers jump quite easily:

beginTime = 0;
endTime = 3.5;
startVal = 29219;
endVal = 20188;

Math.round(linear(time,beginTime,endTime,startVal,endVal)/200)*200

 

The problem is I cant seem to get a comma built in. Not sure if this is because I am trying legacy methods with a JavaScript project. Help if possible. Thank you!

Hi RMI_1,

The new JavaScript expression engine makes formatting numbers very easy, much easier than a 30+ line function. To ensure you're using the JavaScript engine, go to File > Project Settings... > Expressions tab > set "Expressions Engine" to "JavaScript". It's the default so you are likely already using it.

 

Then modify your last line and add one more, as in the following example:

var num = Math.round(linear(time,beginTime,endTime,startVal,endVal)/200)*200;
new Intl.NumberFormat( "en-US", { useGrouping: true } ).format( num );

 

For more information on how to use Intl.NumberFormat, check out https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/NumberFormat. You can format dates, currency, etc and it's all handled by the NumberFormat object. Feel free to reply back with any additional questions.

 

Cheers,

    I just want to say...you're AWESOME! People on YouTube tried so many different ways to achieve this but this expression is perfect for the task at hand! Like, it can't get any better!

     

    For those who don't prefer adding beginning time and end time in the expressions and want to use slider control instead:

    var num = effect("Slider Control")("Slider").value.toFixed();
new Intl.NumberFormat( "en-IN", { useGrouping: true } ).format( num );

    This specific expression is more appreciated by people living outside US as they have different Number Counting System so the comma doesn't always come after 3 digits. You can change "IN" from "en-IN" to your country.

      I almost gave up on my project trying to find this exact expression. Thank you so much!
