_Float128 (and other _FloatNN types) are standard C23 and C++23 types, they certainly can't be simple aliases to __float128 or other similar types. In C++ they mangle differently, have significantly different behavior in lots of different language details. So, you need to implement the https://wg21.link/P1467R9 paper, rather than doing quick hacks. Jakub
