A few weeks ago we reported about a serious excel multiplication bug that was exposed in which Excel 2007 incorrectly multiplied certain numbers. For example, by multiplying 850 by 77.1, you’d receive an answer of 100,000. We know that the answer is really 65,535, and unfortunately, that wasn’t the only number that Excel was having issues with. Microsoft acknowledged the issue, and yesterday they released an update that solves the problem.

Now what’s interesting is that this update is almost 33 MB in size which is large for what would seem to be a simple fix. The Excel blog offers an explanation for the size though, they say “The patch is large because it contains updates for several components that use the Excel logic that showed this issue.” They also explained more specifically which numbers were involved. If a multiplication calculation resulted in an answer of 65534.99999999995 to 65535, it would display an incorrect answer of 100,000.  If a multiplication calculation resulted in an answer of 65535.99999999995 to 65536, Excel would display an incorrect answer of 100,001.

If you’re in a rush to get this issue fixed, below is the direct link to the update. If you don’t really use Excel much, you might as well wait it out because Microsoft says that the update will get automatically pushed out to those using Excel 2007. Service Pack 1 for Office 2007 will also include the update, although no specific release date has been announced for it.
