NaN are not exclusive to JavaScript, it's more scary that they're using floating point numbers for monetary value.
If you buy something at -Inf, do they empty the business bank account into yours?

Eh, it’s not a problem if prices are being converted to floating point at some point before being displayed.

What you don’t want to do is store the definitive price as a floating point and perform calculations with it. I don’t see any reason to assume that’s happening here.

It still makes no sense to convert to float and is likely to lead to a big at some point
