pacman original source code

complement code can be used to process the symbol bit and other digits in a unified manner. At the same time, the subtraction can also be processed by addition. The other two are supplemented.If the highest bit (symbol bit) has a forward bit, the carry is discarded.The conversion process of the complement code is almost the same as that of the original code.The

decimal values directly. The binary value is what it looks like in the computer, and the decimal value is what we represent. Aha, it turns out that this is computable. I used to think that the storage principles of different computers are different depending on the preferences of sellers. Why haven't we mentioned the source code, anti-code, and re-

integers are stored in the form of supplementary codes in the computer. How is the expression of the Supplementary Code? Another concept-anticode, the so-called anticode is to reverse each bit of the negative original code (the negative original code is the same as the

Language .For example: (assuming constants are single-byte)1 + 128, the true value is calculated as 0000 0001 + 1000 0000. If you assign the result to a single byte with a signed positive number, the editor will prompt that you have exceeded the representation range. Because the two data in the operation are unsigned, the result is also 129 of the unsigned, and the maximum value of the signed single-byte variable can be 127.1-128, the truth calculation is 0000 0001 + 1000 0000, because-128 is s

sake of distinction, the real value corresponding to the number of machines with signs is called the true value of the number of machines. For example, the true value of 0000 0001 = + 000 0001 = + 0001 0001 =-000 =-1 Ii. Basic concepts of source code, anti-code and complement codeFor a number, the computer must use a certain encoding method for storage. The

conversion to binary format is 00000011. -3 means 10000011. In this case, 00000011 and 10000011 are the number of machines. 2. True Value Because the first digit is the symbol bit, the form value of the machine number is not equal to the real value. For example, if the above signed number is 10000011, its highest bit 1 indicates negative, and its real value is-3 instead of the form value 131 (10000011 is converted to decimal equal to 131 ). Therefore, for the sake of distinction, the r
