Microsoft® JScript™ ^= Operator | Language Reference Version 1

See Also

##### Description

> Used to perform a bitwise exclusive OR on an expression.

##### Syntax

> result ^= expression

> The ^= operator syntax has these parts:

> Part | Description
> result | Any variable.
> expression | Any expression.

##### Remarks

> Using the ^= operator is exactly the same as specifying:

> >     result = result ^ expression

> The ^= operator looks at the binary representation of the values of two expressions and does a bitwise exclusive OR operation on them. The result of this operation behaves as follows:

> >     0101    (result)
> >     1100    (expression)
> >     ----
> >     1001    (result)

> When one, and only one, of the expressions has a 1 in a digit, the result has a 1 in that digit. Otherwise, the result has a 0 in that digit.

> For information on when a run-time error is generated by the ^= operator, see the Operator Behavior table.
