In keeping with this theme, why not define int() for floats (and other real types) as def __int__(n, method=math.trunc) or something similar, so that, by default, int() provides the same functionality as before (or whatever is decided to be preferred, I'm making no judgements on that end), but has a way --- by passing a different function --- of changing the way it rounds? The other (probably preferred) option, I suppose, would be to provide a few constants (float.FLOOR_METHOD et al.) instead of passing an arbitrary function (which, of course, makes me a bit uncomfortable). -- Cheers, Leif _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
