# std::experimental::ranges::SignedIntegral

From cppreference.com
< cpp‎ | experimental‎ | ranges

Defined in header `<experimental/ranges/concepts>` |  |
template < class T > concept bool SignedIntegral() { return Integral<T>() && std::is_signed<T>::value; } |  | (ranges TS)

The concept SignedIntegral<T>() is satisfied if and only if `T` is an integral type and std::is_signed<T>::value 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).
