Operator

Performs a logical Xor operation on booleans and a bitwise Xor operation on integers.

Usage

result = expression1 Xor expression2

Part	Description
result	A Boolean value if expression1 and expression2 are Boolean; an Integer value if expression1 and expression2 are integers.
expression1	Any valid Boolean or Integer expression. The data types of expression1 and expression2 must match.
expression2	Any valid Boolean or Integer expression. The data types of expression1 and expression2 must match.

Notes

If you use Xor with two booleans, it returns the logical Xor of the booleans. The result table for Xor, Or, and And is:

Expression1	Expression2	Xor	Or	And
True	True	False	True	True
True	False	True	True	False
False	True	True	True	False
False	False	False	False	False

If you use Xor with two booleans, it returns True if the booleans are not equal. The logic is "Not (a=b)". The result is a boolean.

When you pass two integers, it returns an integer that is the result of comparing each bit of the two integers passed and assigning 1 to the bit position in the integer returned if both bits in the same position in the integer passed are not equal. Otherwise, 0 is assigned to the bit position. In this case, it is equivalent to using the BitXor method of the Bitwise class.

The following table shows the results:

Integer1	Integer2	BitAnd	BitOr	BitXor
0	0	0	0	0
0	1	0	1	1
1	0	0	1	1
1	1	1	1	0

Sample Code

This example does a bitwise Xor on the two integers passed.

Dim i As Integer
I = 5 Xor 3 // returns 6
