Is RDF always better than 53-bit RR in this way? If so, perhaps "RealNumber" or the preparser could be changed to use RDF if the precision is sufficiently small. Most users typing 12.345 will want the fastest implementation and not something generic. -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
