Enum member `std.traits.isUnsigned`

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


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

Example

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

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