Used to perform a bitwise exclusive OR on an expression.
result ^= expression
result
Any variable.
expression
Any expression.
Using this operator is exactly the same as specifying:
result = result ^ expression
The ^= operator looks at the binary representation of the values of result and expression and does a bitwise OR operation on them. The output of this operation behaves like this:
0101 (result)
1100 (expression)
----
1001 (output)
When one, and only one, of result or expression have a 1 in a digit, result will have a 1 in that digit, otherwise result will have a 0 in that digit.
For information on when a run-time error is generated by the ^= operator, see the Operator Behavior table.
