From cppreference.com
< cpp‎ | types‎ | numeric limits

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.
