Yes (note that maxNum and minNum were removed in IEEE 754-2019, but they're still what fmax and fmin correspond to; the new minimum / maximum operations in IEEE 754-2019 are provided by new functions in C2x). > Are there builtins for maxNumMag and minNumMag?

I do not want to mess up corners > cases, which is so easy to do… TS 18661-1 defined functions fmaxmag and fminmag for those; we don't have built-in functions for them, and C2x does not include those functions given that those operations were also removed in IEEE 754-2019. -- Joseph S.
