I'm not 100% up to date on the terminology used by the CAS; I hope that isn't confusing matters. I hesitate to use the term "floatingpoint" as (it is my understanding that) the semantics intended by the author of the CAS does not follow that laid out by IEEE 754. (While the Advanced Graphing app does follow IEEE 754 semantics and views finite floatingpoint numbers as exact rational / real numbers, it is fairly common to have different interpretations of values produced using floatingpoint calculations.) I was wondering exactly where the decimal number you gave above for 1519/99 came from, so I'm glad you clarified that. My intention was to do the same division, but I arrived at a different decimal answer.
