Eqv Operator
Calculates the logical equivalence of two expressions.
α‘ααα’αα₯α‘α
Result = Expression1 Eqv Expression2
Parameters:
Result: Any numeric variable that contains the result of the comparison.
Expression1, Expression2: ααααα‘αααα α αͺαα€α α£αα α‘αααααααα αα α‘α’α αα₯ααααα, α αααααααͺ αααααα α¨ααααα αα.
When testing for equivalence between Boolean expressions, the result is True if both expressions are either True or False.
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.
αααααααα:
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 ' returns -1
vOut = B > A Eqv B > C ' returns 0
vOut = A > B Eqv B > D ' returns 0
vOut = (B > D Eqv B > A) ' returns -1
vOut = B Eqv A ' returns -3
End Sub
