^ (bitwise XOR)
Availability
Flash Player 5.
Usage
expression1
^
expression2
Parameters
expression1,expression2
A
number.
Returns
A 32-bit integer.
Description
Operator (bitwise); converts
expression1
and
expression2
to 32-bit unsigned integers, and
returns a 1 in each bit position where the corresponding bits in
expression1
or
expression2
,
but not both, are 1. Floating-point numbers are converted to integers by discarding any digits
after the decimal point. The result is a new 32-bit integer.
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)
