Hello all,

I have audited my formulas over and over and am seeing an odd behaviour in
Excel 2007 SP2. I am comparing cost rates. One contract price will be
0.0140 per minute.Another contract price will be 0.0159.

Each will be compared against the same minute field. Obviously, if you
multiple the first contract price by the minute it will be less than the
second contract price. However, when you add both columns up to get a total
of about 40,000 records, the second contract amount totals less than the
first contract amount. Impossible, right? I even tested with a sumrpoduct
and received the same results. I selected each column, separately and looked
at the auto-calculate value. Once again the larger contract price shows the
smaller total. Can anyone explain.
