# Eqv Operator

Calculates the logical equivalence of two expressions.

## Syntax:

`Result = Expression1 Eqv Expression2`

## Parameters:

\<emph\>Result:\</emph\> Any numeric variable that contains the result of the comparison.

\<emph\>Expression1, Expression2:\</emph\> Any expressions that you want to compare.

When testing for equivalence between Boolean expressions, the result is \<emph\>True\</emph\> if both expressions are either \<emph\>True\</emph\> or \<emph\>False\</emph\>.

In a bit-wise comparison, the Eqv operator only sets the corresponding bit in the result if a bit is set in both expressions, or in neither expression.

## Example:

`Sub ExampleEqv`

`Dim A As Variant, B As Variant, C As Variant, D As Variant`

`Dim vOut As Variant`

`    A = 10: B = 8: C = 6: D = Null`

`    vOut = A > B Eqv B > C REM returns -1`

`    vOut = B > A Eqv B > C REM returns 0`

`    vOut = A > B Eqv B > D REM returns 0`

`    vOut = (B > D Eqv B > A) REM returns -1`

`    vOut = B Eqv A REM returns -3`

`End Sub`
