> And actually, we don't know if the processor used 2's complement or 1's complement -- if it was 1's complement, they would have a signed 0! We can infer it used two's complement, and absolutely rule out one's complement or any signed-zero system, because the range is [-2^15,2^15) and with a signed zero you can't represent every integer in that range in 16-bits, you have one too many unique numbers. |
