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).
