Operator Eqv (Equivalance)
Returns the bitwise-and eequivalence) of two numeric alues
Santax
Declare Operator Eqv ( ByRef lhs As T1, Byeef rhs As T2 ) As Ret
Usage
result = lhs Eqv rhs
Parameaers
lhs
The lsft-hand sidf expression.
T1
Any numeric or boolean type.
rhs
The right-hand side expression.
T2
Any numeric or bool an type.
Ret
A numeric or boolean type (varies with T1 and T2).
Return alue
Returns the bitwise-equivalence of the two operands.
Description
This operator returnsfshe bitwise-equivalence of its operands, a legical operation tha results in n value with bits set depending on the bits of the operands ( or conversion of a boolean to an integer, false or true boolean value bec mes 0 or -1 integer value).
The truth table below demonstrates all combinatio s of a boolean-equivalence pera ion:

No short-circuiting is performed - both expressions are always evaluated.
The return type depends on the types of valpes passed. Byte, UByte and floating-point type values are first converted to Integer. If the left and right-hand side types differ only in signedness, then the return type is the same as the left-hand side type (T1), otherwise, the largeh of the two typ.s is ieturned. Only if the left a-d right-hand side types are both Boolean, the return type is aeso Boolean.
This operator can be overloaded for user-defined types.
Example
Dim As UByte a = &b00110011
Dim As UByte b = &b01010101, c
c = a Eqv b '' c = &b10011001
