There was an exchange on this last year and I posted some links to
articles and web sites that have further information. The post in
question is:

In that same thread, issues were also raised regarding the rounding of
numbers and Excel's implementation of the IEEE 754 standard. There was a
comparison between Excel, Gnumeric and OO.org's Calc with respect to
this issue and I posted some results of that comparison here:

The above post provided some further insight into why Excel and
unfortunately, Calc, behave the way that they do with numbers "close to
zero". As far as I know, the same behavior is still in place today with
the current versions of each application.

HTH,
