std::signed_integral

From cppreference.com
< cpp‎ | concepts
Defined in header <concepts>
template < class T >
concept signed_integral = std::integral<T> && std::is_signed_v<T>;
(since C++20)

The concept signed_integral<T> is satisfied if and only if T is an integral type and std::is_signed_v<T> is true.

[edit] Notes

signed_integral<T> may be satisfied by a type that is not a signed integer type, for example, char (on a system where char is signed).
