64-Bit Bank Balances ‘Ought to Be Enough for Anybody’?
You _can_ use floating point if you are very careful and know what you are doing and know about decimal normalization (see e.g. OpenHFT implementation for high-frequency trading: https://github.com/OpenHFT/Chronicle-Core/blob/ea/src/main/j...)
But if you are not an expert, you better stick to BigDecimal and absorb the performance costs.

This only puts currency codes in the type system; and uses rational numbers for amounts.
This is definitely useful because you can have the type system tell you if you've implemented e.g. exchange rate conversion incorrectly. But it's also a hassle because you need to reify currency values discovered at runtime as types, which isn't pretty [1].
