The results of the bitwise logical operations, where A and B are operands,
and 1 or 0 indicate whether a bit is set or not set:
┌───────────┬────────────────────────────────────────────────────────┐
│ Operands │ Logical operations │
├─────┬─────┼───────┬─────────┬────────┬─────────┬─────────┬─────────┤
│ A │ B │ NOT B │ A AND B │ A OR B │ A XOR B │ A EQV B │ A IMP B │
├─────┼─────┼───────┼─────────┼────────┼─────────┼─────────┼─────────┤
│ 1 │ 1 │ 0 │ 1 │ 1 │ 0 │ 1 │ 1 │
├─────┼─────┼───────┼─────────┼────────┼─────────┼─────────┼─────────┤
│ 1 │ 0 │ 1 │ 0 │ 1 │ 1 │ 0 │ 0 │
├─────┼─────┼───────┼─────────┼────────┼─────────┼─────────┼─────────┤

├─────┼─────┼───────┼─────────┼────────┼─────────┼─────────┼─────────┤

Relational Operations return negative one (-1, all bits set) and zero
(0, no bits set) for true and false, respectively. This allows relational
tests to be inverted and combined using the bitwise logical operations.
