CC @hubert.reinterpretcast @jcranmer-intel > @rsmith `fmin(sNaN, x)` signals FE_INVALID, which would be a compile-time error per [library.c]p3 (every FP exception save FE_INEXACT is a compile-time error). Except sNaN raising FE_INVALID is only a //recommended// practice, so it's really unclear what the C++ standard attempts to say on this matter. Treating sNaN as always signaling FE_INVALID is probably the safer option.
