JavaScript支持以下按位运算符。
例子 (Example)
var a = 2; // Bit presentation 10
var b = 3; // Bit presentation 11
var result;
result = (a & b);
console.log("(a & b) => ", result);
result = (a | b);
console.log("(a | b) => ", result);
result = (a ^ b);
console.log("(a ^ b) => ", result);
result = (~b);
console.log("(~b) => ", result);
result = (a << b);
console.log("(a << b) => ", result);
result = (a >> b);
console.log("(a >> b) => ", result);
成功执行上述程序后，将显示以下输出。
(a & b) => 2
(a | b) => 3
(a ^ b) => 1
(~b) => -4
(a << b) => 16
(a >> b) => 0
