In this topic, we will discuss Bitwise Operators Examples in Typescript.
Assume variable A = 2 and B = 3
| Operator | Description | Example |
|---|---|---|
| & (Bitwise AND) | It performs a Boolean AND operation on each bit of its integer arguments. | (A & B) is 2 |
| | (BitWise OR) | It performs a Boolean OR operation on each bit of its integer arguments. | (A | B) is 3 |
| ^ (Bitwise XOR) | It performs a Boolean exclusive OR operation on each bit of its integer arguments. Exclusive OR means that either operand one is true or operand two is true, but not both. | (A ^ B) is 1 |
| ~ (Bitwise Not) | It is a unary operator and operates by reversing all the bits in the operand. | (~B) is -4 |
| << (Left Shift) | It moves all the bits in its first operand to the left by the number of places specified in the second operand. New bits are filled with zeros. Shifting a value left by one position is equivalent to multiplying it by 2, shifting two positions is equivalent to multiplying by 4, and so on. | (A << 1) is 4 |
| >> (Right Shift) | Binary Right Shift Operator. The left operand’s value is moved right by the number of bits specified by the right operand. | (A >> 1) is 1 |
| >>> (Right shift with Zero) | This operator is just like the >> operator, except that the bits shifted in on the left are always zero. | (A >>> 1) is 1 |
Example
var a:number = 2; // Bit presentation 10
var b:number = 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);
On compiling, it will generate the following JavaScript code −
//Generated by typescript 1.8.10
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);
The output of the above program is given below −
(a & b) => 2 (a | b) => 3 (a ^ b) => 1 (~b) => -4 (a << b) => 16 (a >> b) => 0
