util.Integer.xor

Returns the result of a bitwise XOR on two `INTEGER` values.

Syntax

``````util.Integer.xor(
x INTEGER,
y INTEGER
)
RETURNS INTEGER``````
1. x is an integer value.
2. y is an integer value.

Usage

The `util.Integer.xor()` method makes a bitwise XOR operation with the integer values passed as parameter:
`````` x     : 210 (00000000 00000000 00000000 11010010)
y     : 135 (00000000 00000000 00000000 10000111)
--------------------------------------------------
result :  85 (00000000 00000000 00000000 01010101)``````
Note: Bitwise methods provided by the `util.Integer` class are based on the `INTEGER` type. Consider the following facts when using these methods:
1. The `INTEGER` type is a four-byte signed integer: If the bit at position 31 is set to 1, the corresponding `INTEGER` value will be negative. Thus, `util.Integer.not(0)` produces the `INTEGER` value `-1` (`11111111 11111111 11111111 11111111`).
2. The `NULL` value for the `INTEGER` type is represented internally with the value `0x80000000` (`10000000 00000000 00000000 00000000`). When `NULL` is used with the `util.Integer` bitwise methods, it will be interpreted as `0x80000000` instead of a null value. However, if the result of the bitwise operation produces the value `0x80000000`, it will be interpreted as `NULL` when used in an expression.

Example

``````IMPORT util
MAIN
DISPLAY util.Integer.xor( 6, 2 ) -- displays 4
END MAIN``````
