Bitwise operatorsC provides six bitwise operators. These operators may only allow integer operands, namely char, short, Int, and long, regardless of signed or unsigned.& By-bit and| Bitwise OR^ Bitwise OR> Right shift~ Inverse (unary
Front.
Bitwise operators are very low-level operations and are not commonly used because they are not intuitive. However, its speed is very fast, and reasonable use can achieve very good results. This article will introduce the operator-bitwise
We've explained PHP arithmetic operators, PHP string operators, assignment operators, and today we'll give you a detailed introduction to the PHP operator
"bitwise operator"。
Bit operators are not often used in PHP, but they are still very useful,
1. Expression: The expression is judged to have no result (value), the simplest expression is a constant or variable, such as: A, A, 3 + 1, a + B, a + 5 are expressions2.BOOL (Boolean) data type: In addition to the basic data types in the C language,
in C #, you can perform a bitwise logical operation on an integer operand. The meaning of the bitwise logical operation is that each bit of the operand is taken sequentially, and the logical operation of each bit is the result of each bit of the

Bitwise operators allow us to manipulate a single "bit" in the primary data type of an integer, that is, bits. The bitwise operator performs a Boolean algebra on the corresponding bits in the two arguments and eventually produces a result.Bitwise
Discussion on bitwise operators and displacement operations, and operator displacement operations
I have never understood how to calculate this, because I have never used it before, but now I want to understand it, so it is a good idea to understand
Bitwise operations in Java

Bitwise operators are used to operate binary bits. Java provides bitwise operators as shown below:
