Yeah, I’ve had similar scenarios in frontend projects. Just to add to what @mark-mazay said—if you’re formatting values consistently across a UI, especially for display, using toFixed(2) is pretty much the go-to. It ensures you always get a two-decimal format—even for whole numbers.
So when doing a javascript round to two decimal places, you’re not just rounding; you’re standardizing how the value appears, which is great for things like price tags:
var discount = (100 - (price / listprice) * 100).toFixed(2); // "25.00" instead of "25"
And yeah, convert it with parseFloat() only when you need to do math again.
