TIL about signed overpunch Except the "natural" way also recognizes a single zero with no sign, so it's still not accurately modeling that. If you wanted to model natural arithmetic accurately you'd need 2 bits for the sign (positive, negative, unsigned). At that point, all of single bit signed magnitude, and complements are compromises.
