bitwise or

Today friends in the group asked the next bitwise and/or questions. PHP has been working for 1 years, probably not familiar with this one. Introduce this part to the novice friend here. By being located primarily on the binary number operation.

Bitwise and operations are mainly performed on binary numbers. The following describes the bitwise AND and/or operations in PHP, we hope to help you with bitwise and binary operations. The code is as follows: The code is as follows: $ A = 1;$

Bitwise AND operations are mainly performed on binary numbers.The Code is as follows:Copy codeThe Code is as follows:$ A = 1;$ B = 2;$ C = $ a ^ B;Echo $ c // 3?> This is not a simple addition.Convert decimal 1 to binary 00000001Convert decimal 2 to

In this article, let's take a look at the objective-c bitwise operator . There are various operators in the objective-c language to handle the special positioning in numbers, as shown in the following table: Symbol Operation

Bit operationsThe operation component of the bit operation can only be integer or character data, and the bitwise operation regards the Operation object as a bit string information composed of two digits, completes the specified operation by bit,

Conversion from: c |, |, &, &, Or ,~ ,! Operation Bitwise operation The bitwise operation component can only be integer or numeric type data. bitwise operations regard the operation object as Bit String information consisting of binary digits to

bit arithmeticThe operation component of a bitwise operation can only be integer or character data, and the bitwise operation considers the operand as a bit string information composed of binary bits, and completes the specified operation by bit,

Unary operatorAn operator that can manipulate only one value is called a unary operator. The unary operator is the simplest operator in ECMAScript.1. Increment and decrement operatorsThe increment and decrement operators draw directly from C, and

C language bit operationA bitwise operation is a binary-based operation. In system software, it is often necessary to deal with bits problems. The C language provides 6 bit manipulation operators. These operators can only be used for integer
