If working in currency, work in cents and divide by 100 and round to 2 decimals for output
If working with currency use types and formating functions appropriate for currency. Not float.
I was recalling a project in perl, which doesn't have a variety of types. If you add values, you get a scalar, which will be a float if the numbers are not integers.
I am aware my statement isn't true in several languages
