std::numeric_limits
 
static const bool is_iec559
(hasta C++11)
static constexpr bool is_iec559
(desde C++11)
El valor de std::numeric_limits<T>::is_iec559 es true para todos los tipos de punto flotante T que cumplan los requisitos de la norma IEC 559 (IEEE 754) estándar. Si std::numeric_limits<T>::is_iec559 es true, entonces std::numeric_limits<T>::has_infinity, std::numeric_limits<T>::has_quiet_NaN, y std::numeric_limits<T>::has_signaling_NaN son también true .
Original:
The value of std::numeric_limits<T>::is_iec559 is true for all floating-point types T which fulfill the requirements of IEC 559 (IEEE 754) standard. If std::numeric_limits<T>::is_iec559 is true, then std::numeric_limits<T>::has_infinity, std::numeric_limits<T>::has_quiet_NaN, and std::numeric_limits<T>::has_signaling_NaN are also true.
