Usage
expression1 & expression2
Parameters
None.
Returns
A 32-bit integer.
Description
Operator (bitwise); converts
performs a Boolean AND operation on each bit of the integer parameters. 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 using 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 then have the most significant digits discarded as well.
The return value is interpreted as a two's complement number with sign, so the return is an
integer in the range -2147483648 to 2147483647.

Example
The following example compares the bit representation of the numbers and returns 1 only if both
bits at the same position are 1. In this ActionScript, you add 13 (binary 1101) and 11 (binary
1011) and return 1 only in the position where both numbers have a 1.
var insert:Number = 13;
var update:Number = 11;
trace(insert & update);// output : 9 (or 1001 binary)
