Generate a specific digit or Digit 2. binary encoding format for transmission and storage 3. decodes binary data into a specific format. 2.1 take a specific bit (mask + +>) Use a mask (mask) in a program to obtain a specific bit, for example, for the following binary: 0010 1100 If we start from the third place on the left, we first create the mask: 0010 0000, which is set to 0 except the third place. Then we can get a speci

Bitwise moving OPERATOR: Example: 3 1) Convert 3 to a binary number 0000 0000 0000 0000 0000 0000 0000 0011,2) Remove the two zeros at the upper (left) of the number. All the other digits are shifted to the left,3) Fill in the two vacant positions at the low position (right side. The final result is 0000 0000 0000 0000 0000 0000 0000 1100,Convert to 12 in decimal format. Similarly,> indicates shift right. Shifts one digit right indicates Division 2.

existing standards. As a result, there are so many standards that have the same effect but are not compatible with each other.Said so much we look at a practical example, the following is the 屌 word in various encodings of the 16 binary and binary encoding results, how is there a very cock feeling?Character Set |16 encoding | binary data|-|-|utf-8|0xe5b18c|1110 0101 1011 0001 1000 1100UTF-16|0X5C4C|1011 1000 1001 1000gbk|0x8cc5|1000 1100

first, operator B is updated.A, operator a reads it out at this time (version=1) and adds 100 (1000+100=1100) from its account balance.b, during operator A's operation, operator B also reads this user information (version=1) and deducts 50 (1000-50=950) from its account balance.C, operator a completed the modification work, the data version number plus one (version=2), together with the account increase balance (BALANCE=

In the code of a group of numbers, if any two adjacent code is different from only one binary number, it is called the Gray Code, in addition, because the maximum number and the minimum number is only one digit difference, namely "end-to-end", so also called cyclic code or reflection code. In a digital system, code is often required to change in a certain order. For example, by increasing the number of natural numbers, if the number of 8421 yards, 0111 to 1000 when the four-bit changes, and in t

significant group first. For example, the number 1 is a single byte, so msb is not required: 0000 0001 if it is 300, it must be more complex: 1010 1100 0000 0010 how do you infer that this is 300? First, you should discard the msb of each byte, because msb is only used to tell us whether it has reached the end of the number: 1010 1100 0000 0010→ 010 1100 000 001

decimal is: 2^ (refers to the digit length-1)-1. In this case, the number of digits, the number of digits is the key to the decimal binary operation, with 32-bit floating point as an example, it consists of 1-bit sign bit, 8-bit exponent bit and 23-bit tail digits, the following 32-bit floating-point number:0100 0010 1101 0110 0101 0001 1100 1111Where: digits: 100 0010 1; number of digits: 101 0110 0101 0001
