In addition to performing a logical equivalence, the Eqv operator compares identically positioned bits in two numeric expressions (known as a bit-wise comparison) and sets the corresponding bit in the result according to the following table.
Bit n in expr1Bit n in expr2Bit n in result
1 1 1
1 0 0
0 1 0
0 0 1

Example

Dim a As Variant, b As Variant, c As Variant
a = &HF
b = &HF0
c = &H33
Print TRUE Eqv TRUE               ' Prints True
Print FALSE Eqv FALSE             ' Prints True
Print TRUE Eqv FALSE              ' Prints False
Print Hex$(a Eqv b)               ' Prints FFFFFF00
Print Hex$(a Eqv c)               ' Prints FFFFFFC3
Print Hex$(b Eqv c)               ' Prints FFFFFF3C
