Positive integers are converted to an unsigned hex value with a maximum value of 4294967295 or
0xFFFFFFFF; values larger than the maximum have their most significant digits discarded when
they are converted so the value is still 32-bit. Negative numbers are converted to an unsigned hex
value via the two’s complement notation, with the minimum being -2147483648 or
0x800000000; numbers less than the minimum are converted to two’s complement with greater
precision and also have the most significant digits discarded.
The return value is interpreted as a two’s complement number with sign, so the return value will
be an integer in the range -2147483648 to 2147483647.

Example
The following example uses the bitwise XOR operator on the decimals 15 and 9, and assigns the
result to the variable
x:
// 15 decimal = 1111 binary
// 9 decimal = 1001 binary
var x:Number = 15 ^ 9;
trace(x);
// 1111 ^ 1001 = 0110
// returns 6 decimal (0110 binary)

Usage
expression1 ^= expression2
Parameters
expression1,expression2
Integers and variables.
Returns
A 32-bit integer. Specifically, the value of expression1 ^ expression2.
Description
Operator (bitwise compound assignment); assigns expression1 the value of expression1 ^
expression2. For example, the following two statements are equivalent:
x ^= y
x = x ^ y
