is_integral

template <class T>
struct is_integral : public true_type-or-false_type {};

Inherits: If T is a (possibly cv-qualified) integral type then inherits from true_type, otherwise inherits from false_type.

C++ Standard Reference: 3.9.1p7.

Compiler Compatibility: All current compilers are supported by this trait.

Header: #include <boost/type_traits/is_integral.hpp> or #include <boost/type_traits.hpp>

Examples:

is_integral<int> inherits from true_type.

is_integral<const char>::type is the type true_type.

is_integral<long>::value is an integral constant expression that evaluates to true.

is_integral<T>::value_type is the type bool.
