How to add ".value.toFixed(0)" to a Point Control

You're welcome! There's definitely a lot to learn, and formatting numbers is a tricky one; commas can be especially tricky with the older methods that you might find online.

After Effects added a new, modern JavaScript expression a few years ago which means we now have access to modern JavaScript functions, including a super easy way of formatting numbers and currency. First, make sure you're using the JavaScript Expression Engine from Project Settings > Expressions (this is the default and you should always be using it).

The function is called toLocaleString() and it's incredibly powerful. Here's my template for this expression. You can replace the hard-coded variable values with anything you want, but the way this template works is that over a period of 10 seconds, you'll see the currency animate from 0 to 1000 automatically. The minDigits option is how many decimals you'll get, so you'll want to put "0" there. I swapped the locale and currency for pounds, but if you look at the URLs in the commented lines at the top, you can learn about how to use each of these options.

//locales and options: w3schools.com/jsref/jsref_tolocalestring_number.asp
//currency codes: iban.com/currency-codes

const startCount = 0;
const endCount = 1000;
const countDur = 10;
const count = Math.round( linear(time, 0, countDur, startCount, endCount) );
const minDigits = 2;

const locale = "en-GB";
const options = {
style: "currency",
currency: "GBP",
minimumFractionDigits: minDigits
};

count.toLocaleString( locale, options );
