If you wanted to replicate this behavior without using bitwise operators, it would be the equivalent of using the following math. x * (2 ** y) You would multiply your value by2to the power ofy. “y” in this cas
这篇文章是关于在 Web JavaScript 中如何使用按位与(&)和按位赋值(=)运算符的。按位与运算符(&)用于比较两个操作数的二进制表示,只有当两个相应的位都为1时,结果才为1;否则结果为0。按位赋值运算符(=)用于将一个值赋给一个变量的某个位。 在这篇文章中,作者首先解释了按位与运算符的工作原理,然后...

OperatorsBitwise 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JavaScript中的...
Example: Assignment Operators Copy package main import "fmt" func main() { x, y := 10, 20 //Assign x = y fmt.Println(" = ", x) //output: 20 // Add and assign x = 15 x += y fmt.Println("+= ", x) //output: 35 // Subtract and assign x = 25 x -= y fmt.Println...
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 representation (for ...
