The [EQV](EQV) operator returns a value based on the *equivalence* of two conditions or values.
|

|
|
|
|||
|
|
## Syntax
|
|||
|
|
|
|||
|
|
> result = firstValue [EQV](EQV) secondValue
|
|||
|
|
|
|||
|

## Description
|
|||
|
|
|
|||
|
|
* Returns true (-1) when both values are the same (*equivalent*).
|
|||
|
|
* Turns a bit on if both bits are the same, turns a bit off if both bits are different.
|
|||
|
|
|
|||
|
|
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](NOT)<29>B | A<>[AND](AND)<29>B | A<>[OR](OR)<29>B | A<>[XOR](XOR)<29>B | A<>[EQV](EQV)<29>B | A<>[IMP](IMP)<29>B |

|
**[Relational Operations](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.
