Possibly 21.26 is really 21.2643220... and 6.80 is 6.803452

So, when you add those together, it rounds up.

When I am working in Excel I frequently have noticed simple addition math
functions not calculating correctly -- as simple as $21.26 + $ $6.80
summing up to $28.07 instead of correctly $28.06. I have checked cell
formatting on the cells affected and do not see any formatting issues that
would explain this. Has any one else ever noticed this? It's minor, but I
would like to resolve the issue if any one else has had this happen and can
offer some insight.
