Talk:cpp/types/is unsigned
From cppreference.com
May want to note that even with the new C++11 capability to define the underlying type, using an unsigned type, e.g. unsigned char, does not (and should not) return true:
enum enum_type: unsigned char
{
ENUM_VALUE0,
ENUM_VALUE1
};
is_unsigned<enum_type>::value!=true
Because enum (and enum class) types are not arithmetic.
