Here are bitwise operators that I use, along with sample input and output in base-10, base-2, and base-16.
To generate this table I used a script similar to this, where I would substitute the respective expression for exp.
a = 17, b = 29;
exp = '+';
eval('x = a ' + exp + ' b;');
function format(base) {
return 'Base ' + base + ': ' + a.toString(base)
+ ' ' + exp + ' ' + b.toString(base)
+ ' = ' + x.toString(base);
}
b10 = format(10), b2 = format(2), b16 = format(16);
alert(b10 + '\n' + b2 + '\n' + b16);
| Expression | base-10 | base-2 | base-16 |
|---|---|---|---|
| Bitwise XOR | 17 ^ 29 = 12 | 10001 ^ 11101 = 01100 |
11 ^ 1d = c |
| Bitwise AND | 18 & 29 = 16 | 10010 & 11101 = 10000 |
12 & 1d = 10 |
| Bitwise OR | 18 | 25 = 27 | 10010 | 11001 = 11011 |
12 | 19 = 1b |
| Left shift | 3 << 2 = 12 | 11 << 10 = 1100 | 3 << 2 = c |
| Right shift | 56 >> 3 = 7 | 111000 >> 11 = 111 | 38 >> 3 = 7 |
| Bitwise complement | ~43 = -44 | ~101011 = -101100 | ~2b = -2c |
