Well, never let it be said that we can't have some interesting discussions
on the amsat-bb :-). This started out as a "before coffee" typo on my part,
but it's generated some thinking about exponential notation, etc., so maybe
it's had a useful purpose.

As a graduate of Algebra 101, and a quite a few more math. classes in my
distant past, I find we are in violent agreement ;-).  What you say, and
what Paul said above are both absolutely correct.  Any number to the "zero"
power, including zero, = 1.  The algorithm used in some calculators may not
handle the "zero to the zeroth power" exception. By the way, mine seem to
handle it fine. Because "0.0 e0" is not raising zero to the zeroth power,
it's "0.0 x 10^0" (as Paul indicated above), it should work in your
calculator (and in an orbital program). Why it has been said not to work in
some orbital programs isn't clear, but it shouldn't be a "0^0" problem.
