std::numeric_limits<T>::is_integer: std::numeric_limits<T>::is_integer


std::numeric_limits<T>::is_integer - std::numeric_limits<T>::is_integer


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.
