It is 1 on SunOS 5.8 as well. It's probably a POSIX standard (not that I can easily tell since search engines are still stuck in the alphanumeric stone age ;-), since it is both "right" and "wrong". Anything raised to the zeroth power is defined as 1. Yet anything mulitplied by zero is 0. So they picked something and ran with it?

Question #3
"zero to the zeroth power"

    But in this case, nothing is getting multiplied by zero. So the rule about things being multiplied by zero would not seem to apply here.
    Another way of putting it is that the set of factors is empty. So in this, as in all cases where the set of factors is empty, the answer is 1.
