Operator Eqv= (Equivalence And Assign)operator

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

Operatorsoperatordocumented

Syntax

Declare Operator Eqv= ( ByRef lhs As T1, ByRef rhs As T2 )

Parameters

Name		Description
`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.

Description

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.

Remarks

Usage



lhs Eqv= rhs

Dialect Differences

In the -lang qb dialect, this operator cannot be overloaded.

Example

Dim As UByte a = &b00110011

Dim As UByte b = &b01010101

a Eqv= b

'' Result    a = &b10011001

Print Bin(a)
