You are indeed the gentleman from France and I have indeed greatly appreciated your advice on many issues on these forums.
I did report it yesterday to Apple as an enhancement request. I am just SO close to moving fully to iWork 08. I struggled to get used to how to use pages and have worked with it since the new version came "re-educating" myself, and, finally, yesterday, decided, on balance, it was going to replace Word, until I found the issue noted here.
Unfortunately, though, the biggest things holding me up is just this one feature for numbers. I do not use large spreadsheets, but I have to create large word processor documents in which I put tables with various calculations throughout them out of necessity and, without the precision as displayed feature, the comments I get over and over are "there is an error in your table" on page such and such. The reader then starts to question the reliability of my findings overall.
I just wish there were some simple fix, but it looks like there isn't right now. I may go ahead for now and use numbers and put footnotes below every table that the result is off due to rounding of the individual cell items, but it is not ideal. Otherwise, I truly do like Numbers. At first I found it confusing, but now I really like the independence of the tables on the same sheet which saves lots of hassles that were present in Excel. The slower speed some people complain about is not an issue since I do not have huge spreadsheets usually that require lots of processing and I have not found it slow for my uses.
I can live without the other feature I have been looking into (iteration) and can just use neooffice when a need to do so comes up.
A question, though. It is possible to use scripting or some sort of recorder or automator to do certain tasks in Numbers? I am pretty new to Apple, so I do not exactly understand scripts or the automator ideas yet. Where I can to learn how to use these (really basic explanation) and can I use them in numbers?
