The results of the bitwise logical operations, where A and B are operands, and T and F indicate that a bit is set or not set:
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.
The IMP logical operator converts the result of two comparative values and returns a bit result.
- result = firstValue IMP secondValue
- Returns a different result from AND, OR or XOR.
- Evaluates if firstValue implies secondValue.
- If firstValue is true then secondValue must also be true.
- So if firstValue is true, and secondValue false, then the condition is false, otherwise it is true (see table below).
