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 and remainder, modulo RemainderFor integer a and B, the modulo or remainder operations are all performed: 1. evaluate the integer quotient: c = a/B; 2. modulus or remainder: r = a-c * B. the modulo operation and the remainder operation are
[to] the difference between the modulo operation and the remainder operationIn general, modulo operations (mods) and Redundancy (REM) operations are confused because in most programming languages, the '% ' notation is used to denote modulo or
Typically, modulo operations (MoD) and remainder (REM) operations are confused, because in most programming languages, the '% ' notation is used to represent modulo or remainder operations. Here we want to remind you to pay attention to the specific
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:
I think a lot of people do not know the difference between these two concepts, just in the translation of the LUA manual with the math.fmod of the two operations, by the way to explain it.
The difference between the modulus and the remainder is
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
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,
A very interesting phenomenon has been found today.As a division, Python2 and C + + have different divisible results in the case of negative numbers:When I was 5/3,Results for C + +: 1Results for Python2:2(Note that 5/-3 is still available in C + +-1
Take the remainder in JS

Example
Gets the day, hour, and minute contained in minutes, based on the number of minutes
function Getcosttime (minutes) {var day=parseint (minutes/1440);var hour=parseint (MINUTES/60);var
