Another newbie question

Dear All:

        Even though output_precision = 48 unveils lots of digits for,
say, pi or sqrt(2.0), I found out that only the first 15 are exact
-- the rest seems to be rubbish. I wonder if I am not mistaken, and
if there is no way to show more digits. After all, Windows ME's
Calculator shows pi with 32 correct digits. And should 32-digit
precision is *not* possible, why does Octave show so many useless

Thanks in advance for any help.
