I. For positive numbers, the original code and the reverse code are the same, and all are positive numbers. For negative numbers, the original code is the binary value of the absolute value of X when the symbol bit is 1. The anti-code is that the symbol bit is 1, and the other bit is the reverse of the original

I. Definition1. Original codeThe positive sign bit is 0, and the negative sign bit is 1. The other bits represent the absolute value of the number according to the general method. In this way, the original code of the number is obtained.[Example 2.13] when the machine word length is 8-bit binary:X = + 1011011 [x] source code = 01011011Y = + 1011011 [y] source code
