# std::SignedIntegral

From cppreference.com
< cpp‎ | concepts

Defined in header `<concepts>` |  |
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.

### Notes

`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).
