Subnormals might also need to be considered as special cases: "Whether and in what cases subnormal numbers are treated as zeros is implementation defined." will be added to C23 (some behaviors are dictated by the hardware, e.g. ARM in some non-IEEE configurations), but I've asked for clarification in the CFP mailing-list.
