error on formula results

[Bewilder]

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 should
equal 0.
The problem that i'm having is that the final resultant shown as a negative
0 rounded off to whole No. If I extend the final result to show 30 digits,
somewhere around the 20th. digit numbers show up instead of 0. Where do this
numbers come from and how can I reduce the accuracy of the answer to just 2
digits.

You can use the ROUND function.
