std::numeric_limits::is_integer - cppreference.com (original) (raw)
| static const bool is_integer; | | (until C++11) | | ---------------------------------- | | ------------- | | static constexpr bool is_integer; | | (since C++11) |
The value of std::numeric_limits<T>::is_integer is true for all integer arithmetic types T and false otherwise. This constant is meaningful for all specializations.
