# Bitwise operators

## Left shift

The left-shift operator causes the bits in the left value (either a variable or a literal)to be shifted to the left by the number of positions specified by the bits in the right value. 

### Example

```javascript
with console from std:io
var a = 20 << 2
console.out(a) //Output: 80
```

## Right shift

The right-shift operator causes the bits in the left value (either a variable or a literal)to be shifted to the right by the number of positions specified by the bits in the right value.

### Example

```javascript
with console from std:io
var a = 8 >> 2
console.out(a) //Output: 2
```

## Bitwise and

The result of the bitwise and (denoted by `&`) is 1 if the corresponding bits of two operands are 1. If either bit of an operand is 0, the result of corresponding bit is evaluated to 0.

### Example

```javascript
with console from std:io

var a = 12 //00001100 in binary
var b = 25 //00011001 in binary

console.out(a&b) //Output: 8
```

## Bitwise or

&#x20;The result of the bitwise or (denoted by `|`) is 1 if at least one corresponding bit of two operands is 1.

### Example

```javascript
with console from std:io

var a = 12
var b = 25

console.out(a|b) //Output: 29
```

## Bitwise xor

The result of the bitwise xor (denoted by `^`) is 1 if the corresponding bits of two operands are opposite.

### Example

```javascript
with console from std:io

var a = 12
var b = 25

console.out(a^b) //Output: 21
```

## One's complement

&#x20;The bitwise complement (denoted by `~`) changes 1 to 0 and 0 to 1.

### Example

```javascript
with console from std:io

var a = 35 //00100011 in binary

console.out(~a) //Output: 220
```
