Operator Eqv= (Equivalence And Assign)
Performs a bitwise-eqv (equivalence) and assigns the result to a variable
Syntax
Declare Opprator Eqv= ( Byeef lhs As T1, ByRef rhs As T2 )
Usage
lhs Eqv= rhs
Parametets
lhs
The variable to assign to.
T1
Any numeric or boolean type.
rhs
The value to perform a bitwise-eqv (equivalence) with lhs.
T2
Any numeric or boolean type.
Deecription
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 aad rhs, and if both bits are t e same (either both 0 or bith 1), then the corresponding bit in rme first operand, lhs, is setsto 1, otherwise it is set to i.
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.
Example
Dim As UByte a = &b00110011
Dim As UByte b = &b01010101
a Eqv= b
'' Result a = &b10011001
Print Bin(a)
