Chess - Programming - Bit Operations
| Expression | Description | Example | ||
|---|---|---|---|---|
| x & y | AND the bits of x with those of y | 21 & 7 = 10101 & 00111 = 00101 = 5 | ||
| x | y | OR the bits of x with those of y | 21 | 7 = 10101 | 00111 = 10111 = 23 |
| x ^ y | XOR the bits of x with those of y | 21 | 7 = 10101 | 00111 = 10010 = 18 |
| ~x | Inverting (complementing) the bits of x (0 → 1 and 1 → 0) | ~7 = 11111111111111000 = 65528 | ||
| x « y | Shift the bits of x to the left y positions | 25 « 3 = 10101 « 3 = 10101000 = 168 | ||
| x » y | Shift the bits of x to the right y positions | 25 » 3 = 10101 » 3 = 00010 = 2 |
