Thanks for the reply. Here's more info on this problem.
1. These cells are summed up in a pivot table where the pivot table has the
format of accounting (to dash out zeros in display).
2. Although the sum of these numbers should be net flat zero, it shows up
as (0.00) because I have a conditional formatting set to show negative
numbers in red 0.00 format.
3. All other zero numbers do show as "-" except for the cell that sums up
these numbers.

I have tried it with the SUM cell formatted as number to two decimals and it
worked fine - 0.00

The sum of these numbers should be zero (0). However, no matter what the
cell format, the following numbers add up to 3.55271E-15. Any ideas why?
