The concept of the original code, complement, anti-code
Positive original code: positive absolute value of the original code is a binary number of revolutions, the original code 00000000 00000000 5 is 0,000,000,000,000,101
Negative original code: negative absolute value of the original code is the number of binary turn, and then the sign bit (MSB) plus one, the original code is -5 1,000,000,000,000,000 0,000,000,000,000,101
Positive anti-code: Positive anti-code the same as the original code.
Inverted negative: negative inverted, the number of the original code except the sign bit, inverted. -5 inverted for the 1,111,111,111,111,111 1,111,111,111,111,010
Complement positive number: the number of the same original code.
Negative complement: Yes negative complement its original code in addition to the sign bit (MSB) each bit negated, then add 1 to the lowest level, that is, negative complement. -5 complement code is 1,111,111,111,111,111 1,111,111,111,111,011
induction:
Positive anti-code complement are the same as the original code.
Negative absolute value of the original code is the number of binary turn, and then the sign bit (MSB) plus anti-code for a negative number in addition to the original code symbol bit inversion, negative anti-code complement plus 1 for .
Negative binary number is the negative complement
