They are all only two decimal places.
I am trying to do these databases with
currency. Would the currency have
anything to do with it at all?

That shouldn't have anything to do with it as far as I know.

If the figures are all entered as you showed in your original post then
I would be at a loss to explain the problem.

If any figures are calculated, that's where the discrepancy can arise
between the figures you see and the actual underlying values. If the
*values* are different by the tiniest fraction, you won't get them to
show as equal.

Are any of the figures the result of dividing one number by another?
That often traps me unless I round the results.
