Default Mistery digits on excel

I have created a chart with 2 columns of Nos. and a third column with the
results from the subtraction of column 1 from 2. At the bottom of each colum
I also have the resultant of the column. the display is to 0 digits but the
input on each box is to 2 digits. Also I have selected the numerical to show
in Red and parenthesis if it is a negative No. The final resultant at the
bottom of column 3 should equal 0. I cannot round to display because I would
losse the 2 digit accuracy on the input boxes.
The problem that I'm having is that the final resultant shows a negative
0. If I extend the final result to show max. digits to see why is a negative
0, somewhere around the 20th. digit numbers starts to show up instead of 0's.
Where do these numbers come from? I only inputed to 2 digits, everything else
should be 0. I cannot manipulate the formula to show positive 0 on the
result because if I make an error on the input where the answer would be
truly less than 0, it will not show it. Is there a way to change the setting
to just calculate to 2 significant digits. (Accuracy level) and again, Where
do these numbers come from?
