JavaScriptOperatorsBitwise Operators Bitwise Operators 按位操作符(Bitwise operators) 将其操作数(operands)当作32位的比特序列(由0和1组成),而不是十进制、十六进制或八进制数值。例如,十进制数9,用二进制表示则为1001。按位操作符操作数字的二进制形式,但是返回值依然是标准的JavaScript数值。 下面的表格总结了J...

JavaScript Bitwise OperatorsThe bitwise operators in JavaScript perform operations on the integer values at the binary level. They are used to manipulate each bit of the integer values. Bitwise operators are similar to logical operators but they work on individual bits. ...
Let us first explore the bitwise operators that JavaScript supports. You can use the table below to see each of the supported operators. Alongside each operator, you will see its name, an example, and a description of what the operator does. One important thing to know about JavaScript and ...

The following table summarizes JavaScript's bitwise operators: Signed 32-bit integers The operands of all bitwise operators are converted to signed 32-bit integers in two's complement format. Two's complement format means that a number's negative counterpart (e.g. 5 vs. -5) is all the numb...

Bitwise Operators Bitwise operators perform an operation on the bitwise (0,1) representation of their arguments, rather than as decimal, hexadecimal, or octal numbers. For example, the decimal number eight has a binary representation of 1000. Bitwise operators do their operations on such binary rep...
