# Arduino - Bitwise Operators

Assume variable A holds 60 and variable B holds 13 then −

Operator name Operator simple Description Example
and & Binary AND Operator copies a bit to the result if it exists in both operands. (A & B) will give 12 which is 0000 1100
or | Binary OR Operator copies a bit if it exists in either operand (A | B) will give 61 which is 0011 1101
xor ^ Binary XOR Operator copies the bit if it is set in one operand but not both. (A ^ B) will give 49 which is 0011 0001
not ~ Binary Ones Complement Operator is unary and has the effect of 'flipping' bits. (~A ) will give -60 which is 1100 0011
shift left << Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by the right operand. A << 2 will give 240 which is 1111 0000
shift right >> Binary Right Shift Operator. The left operands value is moved right by the number of bits specified by the right operand. A >> 2 will give 15 which is 0000 1111

## Example

```void loop () {
int a = 10,b = 20
int c = 0;
c = a & b ;
c = a | b ;
c = a ^ b ;
c = a ~ b ;
c = a << b ;
c = a >> b ;
}
```

## Result

```c = 12
c = 61
c = 49
c = -60
c = 240
c = 15
