Enum member `std.traits.isUnsigned`

Detect whether T is a built-in unsigned numeric type.


						
				enum isUnsigned(T)
				 = __traits(isUnsigned, T) && !(is(immutable(T) == immutable(char)) || is(immutable(T) == immutable(wchar)) || is(immutable(T) == immutable(dchar)) || is(immutable(T) == immutable(bool)));

Example

static assert(
    isUnsigned!uint &&
    isUnsigned!ulong
);

static assert(
    !isUnsigned!char &&
    !isUnsigned!int &&
    !isUnsigned!long &&
    !isUnsigned!char &&
    !isUnsigned!wchar &&
    !isUnsigned!dchar
);
