static const bool has_signaling_NaN		(até C++11)
static constexpr bool has_signaling_NaN		(desde C++11)

O valor de std::numeric_limits<T>::has_signaling_NaN é true para todos os tipos T capazes de representar o valor "Signaling Não-A-Número". Esta constante é significativo para todos os tipos de ponto flutuante e é garantido para ser true se std::numeric_limits<T>::is_iec559 == true.

Original:

The value of std::numeric_limits<T>::has_signaling_NaN is true for all types T capable of representing the special value "Signaling Não-A-Número". This constant is meaningful for all floating-point types and is guaranteed to be true if std::numeric_limits<T>::is_iec559 == true.
