Rounding problem R vs Excel

I don't have the reference, but a biologist friend of mine
once showed me a refereed journal article that purported
to demonstrate numerical errors made by MSExcel.  This
would have been Excel97 or Excel2000... In any case, the
journal's scope was biological in nature and the article
was of interest since Excel is heavily used in that community.

@ARTICLE{McCull99,
   AUTHOR = {McCullough, B. and Wilson, B.},
   TITLE = {On the Accuracy of Statistical Procedures in Microsoft Excel
97},
   JOURNAL = "Comp. Stat. \& Data Anal.",
   VOLUME  = 31,
   NUMBER  = 1,
   YEAR    = 1999,
   PAGES   = {27-37}
}

I seem to remember that there was a follow-up article (note?) in CSDA
regarding the persistence of the problems in Excel 2000.
