IMP - QB64Official/qb64 GitHub Wiki
The IMP logical operator converts the result of two comparative values and returns a bit result.
Syntax
result = firstValue IMP secondValue
Description
- Returns a different result from AND, OR or XOR - see truth table below.
- 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).
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:
| A | B | NOT�B | A�AND�B | A�OR�B | A�XOR�B | A�EQV�B | A�IMP�B | |
|---|---|---|---|---|---|---|---|---|
| T | T | F | T | T | F | T | T | |
| T | F | T | F | T | T | F | F | |
| F | T | F | F | T | T | F | T | |
| F | F | T | F | F | F | T | T |
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.
