Operator Eqv= (Equivalence And Assign)
Performs a bitwise-eqv (equivalence) and assigns the result to a variable
lhs Eqv= rhs
lhs
This operator performs a bitwise-eqv and assigns the result to a variable. It is functionally equivalent to:
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.
Syntax
Usage
lhs Eqv= rhs
Parameters
lhs
The variable to assign to.
T1Any numeric type.
rhsThe value to perform a bitwise-eqv (equivalence) with lhs.
T2Any numeric type.
Description
This operator performs a bitwise-eqv and assigns the result to a variable. 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.
Example
Dim As UByte a = &b00110011
Dim As UByte b = &b01010101
a Eqv= b
'' Result a = &b10011001
Print Bin(a)
Dim As UByte b = &b01010101
a Eqv= b
'' Result a = &b10011001
Print Bin(a)
Dialect Differences
- In the -lang qb dialect, this operator cannot be overloaded.
Differences from QB
