Unless Jed figures out a way to do it the current model is that with quad they are printed wrong and you need to manage their display yourself.

So libquadmath introduces the Q type qualifier so you can use %Qe, %Qf, %Qg. Unfortunately libc is behind the times unless you have a bleeding-edge version (inconvenient without disrupting the rest of your system). To deal with not having a new enough libc, you can use quadmath_snprintf: char buf[256]; quadmath_snprintf(buf,sizeof buf,"%Qg",my_float128);
