Operator XOR= (Exclusive Disjunction and Assign)


Performs a bitwise-xor (exclusive disjunction) and assigns the result to a variable

Syntax:
declare operator Xor= ( byref lhs as T1, byref rhs as T2 )

Usage:
lhs Xor= rhs

Parameters:
lhs
The variable to assign to.
T1
Any numeric or boolean type.
rhs
The value to perform a bitwise-xor (exclusive or) with lhs.
T2
Any numeric or boolean type.

Description:
This operator performs a bitwise-or 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 xor rhs

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

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

Examples:
Dim As UByte a = &b00110011
Dim As UByte b = &b01010101
a Xor= b
'' Result    a = &b01100110
Print Bin(a)
