### Modulo 2 Operation principle modulo 2 addition, modulo 2 subtraction, modulo 2 multiplication, modulo 2 division

Modulo 2 is a binary algorithm, the core ofCRC calibration technology, so before we analyze the CRC algorithm, we must grasp the rules of modulo 2 operation. In the same way as arithmetic, modulo 2 also includes modulo 2 plus, modulo 2 minus, modulo

### Modulo 2 operation

1. What is modulo 2 operation? First of all, what is modulo 2? Modulo: The remainder, then, modulo 2, is divided by 2 to obtain the remainder. Again, what is arithmetic? is subtraction. That is, the modulo 2 operation, can be opened up in this way:

### In simple terms, CRC-modulo 2 Operation

Key words: CRC algorithm principle; CRC verification; modulo 2 (mod 2); mod 2The CRC verification algorithm adopts a binary algorithm called "modulo 2 operation. The modulo 2 operation is the core part of the CRC operation. Therefore, before

### Principle of modulo 2 operation

Modulo 2 is a binary algorithm, the core of CRC calibration technology, so before we analyze the CRC algorithm, we must grasp the rules of modulo 2 operation. In the same way as arithmetic, modulo 2 also includes modulo 2 plus, modulo 2 minus,

### Negative modulo operation

Summary: We know that in different languages, the results of negative number modulo operations may be different. For example, (-11) % 5 calculates 4 in Python and-1 in C (c99. Truncate division floor division in most programming languages, if the

### Modulo n operation

Note: This is just my personal understanding. It may be incorrect. For integers A and N, the modulo n operation is to calculate the remainder of a divided by N. If a = 10, n = 3, the quotient of a divided by N is 3, and the remainder is 1. C
