See <http://srfi.schemers.org/srfi-60/srfi-60.html>. Bitwise operations on integers (both positive and negative) are well defined and implementable in pure R4RS using no more bits than the input numbers. _______________________________________________ Scheme-reports mailing list [email protected] http://lists.scheme-reports.org/cgi-bin/mailman/listinfo/scheme-reports
