Ted, The most recent work on this that I know of, that includes Calc, is: On the Numerical Accuracy of Spreadsheets Marcelo G. Almiron, Bruno Lopes, Alyson L. C. Oliveira, Antonio C. Medeiros, Alejandro C. Frery JSS Vol. 34, Issue 4, Apr 2010 http://www.jstatsoft.org/v34/i04 There have been some discussions on R-Help in the past (circa 2003), which I have participated in, which discuss some of the faults in Calc, such as rounding numbers "close to 0" to 0 (like Excel does) and some of the non-IEEE 754 floating point behavior (like Excel does)...
