Excel multiplication bug gets a patch

— 2:05 PM on October 10, 2007

Last month, we reported on a bug in Microsoft Excel 2007 that causes some multiplications to return erroneous results. The multiplications include 7.1*850, 5.1*12850, and 10.2*6425, and while they're all meant to return results of either 65,535 or 65,536, Excel 2007 returns a result of 100,000 instead.

As CNet reports, Microsoft has now issued a fix for the problem. The fix is available to download from a posting on the Microsoft Excel blog for both Excel 2007 and Excel Services 2007 in its 32-bit and 64-bit versions. Additionally, Microsoft has published knowledge base articles about the Excel 2007 and Excel Services 2007 bugs. The blog posting says Microsoft is currently in the process of adding the fix to Microsoft Update so it can be automatically installed by Excel users, and the company says the fix will be included in the first service pack for Office 2007.
