Microsoft Excel 2007 Calculation Issue

Update

Microsoft has now posted a hotfix package to its Web site that corrects this flaw in Excel 2007 and Excel Services 2007. The fix will be offered soon through Microsoft Update so that users can get the patch automatically without having to go to Microsoft's site.

In late September 2007, Microsoft confirmed that there is floating point issue involving calculations of numbers around 65,535 in Excel 2007. The first reported example of the error in Excel 2007 was that the formula =77.1 * 850 would return the value of 100,000 instead of the correct answer of 65,535. Other calculations have since been identified that also create the error. The issue only exists in Excel 2007, not previous versions
