IMP - mkilgore/QB64pe GitHub Wiki

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 - 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 true or false 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 true true false true true false true true true false true false true true false false false true false false true true false true false false true false false false true true

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.

• Boolean
