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).
