Definido no cabeçalho `<type_traits>`

`template< class T > struct is_integral;`		(desde C++11)

Se T é um tipo integral (bool, char, char16_t, char32_t, wchar_t, short, int, long, long long, incluindo qualquer assinado, não assinado, e cv qualificados variantes), fornece o membro constante value true igual. Para qualquer outro tipo, é value false.

Original:

If T is an integral type (bool, char, char16_t, char32_t, wchar_t, short, int, long, long long, including any signed, unsigned, and cv-qualified variants), provides the member constant value equal true. For any other type, value is false.
