Detailed Description

template<typename T>
class bsl::is_signed< T >

If the provided type is a signed type (taking into account const qualifications), provides the member constant value equal to true. Otherwise the member constant value is false.

#include <bsl/is_signed.hpp>
#include <bsl/debug.hpp>

namespace bsl
{
    inline void
    example_is_signed_overview() noexcept
    {
        if (bsl::is_signed<bsl::int32>::value) {
            bsl::print() << "success\n";
        }
    }
}

Note

We only support the cstdint.hpp basic fixed-width types which is different compared to the standard library version of this type trait. This is because, the fixed-width types are the only types that we support.

Template Parameters

T	the type to query
