And that a default float NaN, converted to double, may not be the same as
a default double NaN - but if you don't care about NaN payloads anyway,
that probably doesn't matter.
TS 18661-1 and C2x (Annex F only, not in the main standard) define
setpayload functions to return a NaN with a given payload in a portable
way.
