Multiplication Bug in Excel 2007

[paul]

As reported by a member of google group forum there is serious bugs in excel 2007, for example 850 * 77.1 gives a result of 100,000 instead of the correct 65,535. Another poster of that forum reported this behaviour as well;

"Suppose the formula is in A1. =A1+1 returns 100,001, which appears to show the formula is in fact 100,000... =A1*2 returns 131,070, as if A1 had 65,535 (which it should have been). =A1*1 keeps it at 100,000. =A1-1 returns 65,534. =A1/1 is still 100,000. =A1/2 returns 32767.5."
