Yes you can. You’re vastly underestimating the size of an f64. Give me a concrete example of a money operation that fails with f64 (for normal companies; assuming you aren’t a stock exchange or Visa or whatever).
Enums are not a good idea for the currencies either.

0.1f64 + 0.2f64 != 0.3f64
Why not?
Encoding in assumptions about a fixed amount of supported currencies in a system is broadly speaking not a good idea

It does if you round it to the nearest penny.
Most sensible programming languages allow enums to be non-exhaustive.
