Machine numbers include three representations: original code, one's complement and complement. The original code is a binary number with a sign bit added. The sign bit of a positive number is 0, the sign bit of a negative number is 1, and the sign bit is the highest bit; the complement of a positive number is its original code, and the complement of a negative number is the sign bit.
