It may be one of the "short operands and long accumulator" kind. Or it just may involve many multiplications by short integers (by 2, for example - very frequent pattern). > Writing the conversion code in lisp is not difficult.

So it is takes some time to determine whether it fits into int32/int64. -- With best regards, Sergey mailto:sergey.bochka...@alglib.net -- 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
