Alias std.traits.Signed
Returns the corresponding signed type for T. T must be a numeric integral type, otherwise a compile-time error occurs.
Declaration
alias Signed(T) = ModifyTypePreservingTQ!(Impl,OriginalType!T);
Example
alias S1 = Signed!uint;
static assert(is(S1 == int));
alias S2 = Signed!(const(uint));
static assert(is(S2 == const(int)));
alias S3 = Signed!(immutable(uint));
static assert(is(S3 == immutable(int)));
static if (is(ucent))
{
alias S4 = Signed!ucent;
static assert(is(S4 == cent));
}
