floor function for GiNaC::numeric

Hi, I've looked through the documentation and header files for GiNaC::numeric and I haven't been able to find the floor (or ceil, for that matter) function for that class. Have I overlooked something, or is that missing? How can I implement one? I know CLN has a floor1 function that is what I want. -- So far we've managed to avoid turning Perl into APL. :-) -- Larry Wall in <199702251904.LAA28261@wall.org> Eduardo M Kalinowski (ekalin@iname.com) http://move.to/hpkb http://cami-ufpr.hpg.com.br - To UNSUBSCRIBE, email to ginac-list@ginac.de with a subject of "unsubscribe".
