Operator EQV= (Equivalence and Assign)

Performs a bitwise-eqv (equivalence) and assigns the result to a variable

declare operator Eqv= ( byref lhs as T1, byref rhs as T2 )

lhs Eqv= rhs

The variable to assign to.
Any numeric or boolean type.
The value to perform a bitwise-eqv (equivalence) with lhs.
Any numeric or boolean type.

This operator performs a bitwise-eqv and assigns the result to a variable (for conversion of a boolean to an integer, false or true boolean value becomes 0 or -1 integer value). It is functionally equivalent to:
lhs = lhs eqv rhs

Eqv= compares each bit of its operands, lhs and rhs, and if both bits are the same (either both 0 or both 1), then the corresponding bit in the first operand, lhs, is set to 1, otherwise it is set to 0.

This operator can be overloaded for user-defined types as a member Operator using the appropriate syntax.

Note: Similarly to the operator '=[>]' (assign), the alternative symbol 'Eqv=>' can be also used.

Dim As UByte a = &b00110011
Dim As UByte b = &b01010101
a Eqv= b
'' Result    a = &b10011001
Print Bin(a)
