Storage, retrieval, transmission, and serialization/deserialization systems should be able to transmit and round-trip floats without losing any bits at all.

[hansonkd]

Floats break the basic expectation of == for round-trip verification, not due to programmer error, but because NaN is non-reflexive by spec. A bit-perfect round-trip can reproduce the exact bit pattern and still fail an equality check. The problem is intrinsic to the type, not the operator.
