First, Location codeIn order to adapt to the need of computer processing Chinese character information, China promulgated the GB2312 National Standard in 1981.

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
