std::numeri...has_infinity(3) C++ Standard Libarystd::numeri...has_infinity(3) NAME std::numeric_limits::has_infinity - std::numeric_limits::has_infinity Synopsis static const bool has_infinity; (until C++11) static constexpr bool has_infinity; (since C++11) The value of std::numeric_limits<T>::has_infinity is true for all types T capable of representing the positive infinity as a distinct special value. This constant is meaningful for all floating-point types and is guaranteed to be true if std::numeric_limits<T>::is_iec559 == true. Standard specializations T value of std::numeric_limits<T>::has_in- finity /* non-specialized */ false bool false char false signed char false unsigned char false wchar_t false char8_t (C++20) false char16_t (C++11) false char32_t (C++11) false short false unsigned short false int false unsigned int false long false unsigned long false long long (C++11) false unsigned long long (C++11) false float usually true double usually true long double usually true See also infinity returns the positive infinity value of the given floating-point [static] type (public static member function) has_quiet_NaN identifies floating-point types that can represent the special [static] value "quiet not-a-number" (NaN) (public static member constant) has_signaling_NaN identifies floating-point types that can represent the special [static] value "signaling not-a-number" (NaN) (public static member constant) http://cppreference.com 2022.07.31 std::numeri...has_infinity(3)
