Excel sheet calculation problem

See the attached sheet.  When I select column C, the sum is 5.68434E-13. Why?  The sum should be zero.  Normally I can click on C and it will give an accurate sum.  What do I need to address? 51003EE.xls

Not sure that you can change what it shows on the status bar....that just reflects the value you get if you use the formula = SUM(C:C)

That amount is a number very close to zero, the reason it isn't zero is to do with the way Excel calculates - it can sometimes result in small "precision errors". You can get the correct sum in a cell by rounding e.g.

Hi Barry,

Ket me clarify what I am asking. I have for several years now simply clicked on the C column and the sum of that column appears at the bottom of my window.  That always works and it is always accurate. A few days ago something happened where I import a few lines of data and every since then the C column has that weird " 5.68434E-13" instead of the actual number.  Here's another wierd thing: if I delete a row, it will sum correctly. Any row, not just a particular row, but delete any row and the sum works.  Ok, now that I am articulating this, I think I may realize what you are saying....are you saying the weird " 5.68434E-13" is excels way of saying "zero"?
