--- Comment #2 from g.peterh...@t-online.de ---
I think there is a misunderstanding. The problem is that std::fmin/std::fmax
and quadmath fminq/fmaxq give different results when only *one* argument is
signaling_NaN.
The standard (https://en.cppreference.com/w/cpp/numeric/math/fmin +
https://en.cppreference.com/w/cpp/numeric/math/fmax) says:
* If one of the two arguments is NaN, the value of the other argument is
returned
* Only if both arguments are NaN, NaN is returned
quadmath fminq/fmaxq also return NaN if only *one* argument is signaling_NaN.
