Re: PowerPC IEEE 128-bit floating point: Language standards

I have not been following the language standards recently.  For any of the

(such as __float128)?

C++ doesn't require any particular value representation for arithmetic types. But std::numeric_limits<long double>::is_iec559 will let you know whether it conforms or not.
