Description:
Used to perform a logical exclusion on two expressions.
Syntax:
result = expression1 Xor expression2
Note:
If one, and only one, of the expressions evaluates to
true, then result is
true. The result is determined according to the following table:
| expression1: |
expression2: |
result: |
| true |
true |
false |
| true |
false |
true |
| false |
true |
true |
| false |
false |
false |
The operator 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 bit in result is: |
| 0 |
0 |
0 |
| 0 |
1 |
1 |
| 1 |
0 |
1 |
| 1 |
1 |
0 |
The
Xor operator executed for
multiple expressions simultaneously (e.g.
v1 Xor v2 Xor ... Xor vN) returns:
- true if the number of expressions is uneven (N is uneven number)
- false if the number of expressions is even (N is even number)
