New submission from Steven D'Aprano <st...@pearwood.info>: In the PEP for Decimal, it was discussed that the class should have a from_float() method for converting from floats, but to leave it out of the Python 2.4 version: http://www.python.org/dev/peps/pep-0327/#from-float
Following discussions with Mark Dickinson, I would like to request that this now be implemented. The suggested API is: Decimal.from_float(floatNumber, [decimal_places]) At the risk of derailing the request, I wonder whether it is better to give a context rather than a number of decimal places? Pro: better control over conversion, as you can specify rounding method as well as number of decimal places. Con: more difficult for newbies to understand. Semi-pro: float to decimal conversions are inherently tricky, perhaps we should be discouraging newbies from blindly calling from_float() and make the (hypothetical) context argument mandatory rather than optional? ---------- components: Library (Lib) messages: 78664 nosy: stevenjd severity: normal status: open title: Decimal to receive from_float method type: feature request _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue4796> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
