std::numeric_limits<T>::is_iec559の値は、すべての浮動小数点型trueIEC 559（T）規格の要求事項を満たすためIEEE 754です。 std::numeric_limits<T>::is_iec559trueであれば、std::numeric_limits<T>::has_infinity、std::numeric_limits<T>::has_quiet_NaN、そしてstd::numeric_limits<T>::has_signaling_NaNもtrueです.

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.
