Nobody here really discussed the history, and I don't know. The questions here have been about what to do given that `is_integer` and `as_integer_ratio` are _already_ advertised (public) methods on some numeric types. > If the answer is - consistency upon the numeric tower - will it go > for complex type and what will it mean (there can be two point of views)? I haven't seen anyone suggest either method be added to Complex. There are lots of methods that don't show up in the tower before hitting Real. For example, given that Complex doesn't support __float__, it would be bizarre if it _did_ support as_integer_ratio. > Is this functionality so often used and practical to be a method of float, > int, ..., and not just to be an auxiliary function? > > p.s.: The same thoughts about `as_integer_ratio` discussion. I would have added them as functions in the `math` module instead. perhaps supported by dunder methods (__as_integer_ratio__, __is_integer__). But that's not what happened, and whether or not they have double underscores on each end doesn't really make all that much difference except to dedicated pedants ;-) _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
