Performs a logical exclusion on two expressions.
result = expression1 Xor expression2
If one, and only one, of the expressions evaluates to True, result is True. However, if either expression is Null, result is also Null. When neither expression is Null, result is determined according to the following table:
If expression1 is | And expression2 is | Then result is |
---|---|---|
True | True | False |
True | False | True |
False | True | True |
False | False | False |
The Xor operator also performs a bitwise comparison of identically positioned bits in two numeric expressions and sets the corresponding bit in result according to the following table:
If bit in expression1 is | And bit in expression2 is | Then result is |
---|---|---|
0 | 0 | 0 |
0 | 1 | 1 |
1 | 0 | 1 |
1 | 1 | 0 |
