Has MS ever fixed the bad arithmetic implementation Excel used, that produced explicitly wrong answers for ordinary computations? Maybe an optional setting for a worksheet "Produce right answers"? And, "New worksheets should have 'Produce right answers' set"?
(I don't recall the details about the bad arithmetic.)
Probably you should give an example. Afaik, there was never an issue about computational accuracy and you should be knowing that almost fortune 500 companies use it for their day to day sales/financial data
