Hi @Anonymous
Looking at the documentation. I can only see seven data types

With the help of JavaScript and the combination of liquid. I played around with your scenario. Posting here as a reference
In your page HTML area. PFB self-explanatory
{% assign Price = "5557365.56565" %}
<script>
$( document ).ready(function() {
var itemPrice = '{{Price}}';
console.log(new Intl.NumberFormat('en-US', { style: 'currency', currency: 'USD' }).format(itemPrice));
var formattedItemPrice = new Intl.NumberFormat('en-US', { style: 'currency', currency: 'USD' }).format(itemPrice);
console.log(555, formattedItemPrice);
$('#myTag').empty().append(formattedItemPrice);
});
</script>
In your HTML tag have an id tag like below
<div class="row sectionBlockLayout" style="text-align: left; min-height: 100px; padding: 8px; margin: 0px;">
<div class="container" style="display: flex; flex-wrap: wrap;">
<div class="col-md-12 columnBlockLayout">
<h3 id="myTag"> Price here </h3>
</div>
</div>
</div>
Note: H3 element has myTag id
Hit Save> Sync Config and Browse the website ( Ctrl + F5)
Output:

Hope it helps.
