Hi
and just for the fun of it the result for your original formula would
be
-0.240375 - 0.416342i

Hi all,
I have run across one of my project and could not figure this out.
This is mathematically correct, totally, but excel could not give me
the desired answer:
(-3)^(-2/3) returns #NUM!, but
((-3)^(-2))^(1/3) is ok.
This leads to other problems also if you have time to change the base
for the power function (negative and possitive)

I am using Microsoft XP Professional.
Thanks,
Lmn.
