It's clear that even the smallest implementations such as Chibi can support the full tower; the ones that don't do so, don't because they have other concerns such as ease of implementation. See <http://trac.sacrideo.us/wg/wiki/NumericTower> for a list of which implementations do what. The question is, what should a Scheme application programmer be entitled to rely on having when they start to use a Scheme implementation intended for the ordinary needs of (non-embedded) application programming? > but wouldn't it in principle be a Good Thing if in the Scheme numeric > tower the various aspects were orthogonal? In principle, yes. However, innovation is not the point of standardization except where it can't be avoided. As you can see at the NumericTower page, I have factored the tower into four orthogonal ideas: unbounded integers, unbounded rationals, inexact numbers, and complex (non-real) numbers. But this was a post hoc attempt to make sense of what already existed. -- John Cowan http://www.ccil.org/~cowan [email protected] Wer es in kleinen Dingen mit der Wahrheit nicht ernst nimmt, dem kann man auch in grossen Dingen nicht vertrauen. --Albert Einstein on honesty _______________________________________________ Scheme-reports mailing list [email protected] http://lists.scheme-reports.org/cgi-bin/mailman/listinfo/scheme-reports
