I doubted the usefulness of exact complex numbers - wouldn't they be manipulated in ways that produce inexact results anyway - but then I realized/found out that they exist in number theory as "Gaussian integers" and "Gaussian rationals" and are of some interest as such. So, if I may, I vote 1) yes 2) yes for requiring exact rational arithmetic, and 3) yes 4) yes for requiring complex numbers, both exact and inexact. _______________________________________________ Scheme-reports mailing list [email protected] http://lists.scheme-reports.org/cgi-bin/mailman/listinfo/scheme-reports
