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
