expression1
|
expression2
Converts
expression1
and
expression2
to 32-bit unsigned integers, and returns a 1 in each
bit position where the corresponding bits of either
expression1
or
expression2
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.

Operands
expression1 :
Number
- A number.
expression2 :
Number
- A number.
Returns
Number
- The result of the bitwise operation.
Example
The following is an example of a bitwise OR (|) operation:
// 15 decimal = 1111 binary
var x:Number = 15;
// 9 decimal = 1001 binary
var y:Number = 9;
// 1111 | 1001 = 1111
trace(x | y); // returns 15 decimal (1111 binary)
Don't confuse the single | (bitwise OR) with || (logical OR).
