Despite the ugliness of floating point arithmetic (lack of associativity, for example) and my general distaste for it, I would have to agree that 64-bit floats are higher precision than 32-bit fixed-points, since more than half the bits are mantissa. Do major currency traders really store money as 64-bit floats? It surprises me. By the way, I thought the "get real" pun was funny and not at all disparaging. But I hope that "get rational" is good enough for currency exchange.
