Bitwise logical multiplication (conjunction). Set the output value as a result of logical multiplying, applied to each pair of bits, which are at the same positions in the binary representation of the input values.
In other words, the output is:
- "1" if both respective bits of input value are equal to "1";
- "0" if at least one bit of the pair is "0".
For example:
| value X | = | 27 | = | 0x001B | = | 0b0000000000011011 |
| value Y | = | 58 | = | 0x003A | = | 0b0000000000111010 |
| Result | = | 26 | = | 0x001A | = | 0b0000000000011010 |
Features
Operation 'Bitwise AND' is used to mask — select specific bits or fields of several bits of binary number.
