The previous blog briefly introduced the computer Central Plains code, back code, complement and shift code representation (http://blog.csdn.net/xdd19910505/article/details/40424533), for the computer why it is not very clear, it seems to know such a thing, but I don't know why. It's like a person you don't know, he's not his friend, you don't know what he's ....
Values have positive and negative values, and the computer uses the highest bit of a number to store the symbols (0 is positive, 1 is negative ). this is the original code of the number of machines. assume that the number of digits processed by the machine is 8. that is, the word length is 1 byte, and the original code can indicate the value range is 127 ~ (-127)Source
See a lot of people need, put it out, good things to share with everyone.
