a new update of our comparison is available:
https://members.loria.fr/PZimmermann/papers/accuracy.pdf
Main changes in this update:
* we have added compoundn, pown and rootn* GNU libc is the first library to provide all new C23 functions* GNU libc now provides 31 correctly-rounded functions in single precision
As for FreeBSD, we saw no big changes between 14.2 and 14.3.
