The Corpus Callosum

Microsoft Big Flub

One of their flagship products, Excel , has been caught
making errors doing simple multiplication.  According
to a Microsoft Developer blog

Yesterday evening we were alerted to an
issue in Excel 2007 (and Excel Services 2007) involving calculation of
numbers around 65,535.  The first example that we heard about
was =77.1*850, but it became clear from our testing as well as
additional reports that this was just one instance where Excel 2007
would return a value of 100,000 instead of 65,535.
