AutoSum lost a penny
Hi I am trying to use autosum to add up a colum of figures but it keeps
loosing a penny. for example £551.99 £459.99 £402.49 £344.99 £632.44 £114.99 £52.89 when these totals are added together on a calculator the total is 2559.78 but when I use autosum the total appears as 2559.77. Please can anyone shed any light as to why this may be. I have checked that there are no other characters in the cells or formula. |

Calculate for yourself the exact binary representation of 551.99, and that
will explain the problem. [Hint: there isn't an exact binary representation of most decimal numbers. 0.5 you are OK, 0.25 yes, but 0.1 no.] http://www.mcgimpsey.com/excel/pennyoff.html -- David Biddulph "PoldenKaz" wrote in message ...

Thanks for your reply. It was most helpful. The instructions in your link
were for an older version of excel and so it took me some time to find where the instructions led to. For anyone who has the same problem and are using excel 2007 they need to click on the Office button/excel options/advanced and browse to 'when calculating this workbook' and click set precision as displayed.
