template < class T > concept SignedIntegral = std::Integral<T> && std::is_signed_v<T>; | (since C++20) |

The concept `SignedIntegral<T>`

is satisfied if and only if `T`

is an integral type and `std::is_signed_v<T>`

is `true`

.

`SignedIntegral<T>`

may be satisfied by a type that is not a signed integer type, for example, `char`

(on a system where `char`

is signed).

(C++11) | checks if a type is an integral type (class template) |

(C++11) | checks if a type is a signed arithmetic type (class template) |
