Myers --- Note also that in glibc, _Float128 support in printf code can only be used = in limited circumstances: either on powerpc64le, as one of the multiple suppor= ted long double formats there, or through the sharing of the printf code with t= he implementation of strfromf128. In particular, there are no glibc printf formats corresponding directly to _FloatN / _FloatNx types. There was support in principle at the WG14 meetin= g in Strasbourg in January for having some form of printf/scanf support for such types in C2y, but major work is still needed on the wording that was propos= ed in N3184.=
