Used to perform a logical equivalence on two .

Syntax

result = expression1 Eqv expression2

The Eqv operator syntax has these parts:

Part Description
result Required; any numeric .
expression1 Required; any expression.
expression2 Required; any expression.

Remarks

If either expression is , result is also Null. When neither expression is Null, result is determined according to the following table:

If expression1 is And expression2 is The result is
True True True
True False False
False True False
False False True

The Eqv operator performs a of identically positioned bits in two and sets the corresponding bit in result according to the following table:

If bit in expression1 is And bit in expression2 is The result is
0 0 1
0 1 0
1 0 0
1 1 1

Example

This example uses the Eqv operator to perform logical equivalence on two expressions. 

Dim A, B, C, D, MyCheck A = 10: B = 8: C = 6: D = Null ' Initialize variables. MyCheck = A > B Eqv B > C ' Returns True. MyCheck = B > A Eqv B > C ' Returns False. MyCheck = A > B Eqv B > D ' Returns Null. MyCheck = A Eqv B ' Returns -3 (bitwise comparison).
