Hello Eike, after a quick test it seems that excel allows values up to 1E10. I'm open for suggestions but 1E5 is definitely much too low. We should choose a value between 1E10 and 1E14 if we really want to add an upper limit. I'm open for any suggestions.

Does Excel impose some upper bound on that parameter? If so, we should compare its output near such value with Calc's, and if sufficiently "equal" maybe raise the bound. Another approach would be to compare with Mathematica, Regina is known to love such work ;-) Eike -- PGP/OpenPGP/GnuPG encrypted mail preferred in all private communication.
