Those numbers are straight from a test I did on my machine. If you look at
those numbers expressed in binary, you can see that a bitwise and will
return 0, as there is only one bit set to 1 in the second number, and the
corresponding bit in the first number is a 0, hence the result of the
bitwise and is 0.
If perl gives you a different number, then perl either wasn't doing a
bitwise and (though the perl docs say otherwise), or you were using
different numbers...
cheers!
