New submission from Serhiy Storchaka <storchaka+cpyt...@gmail.com>:
There are two interfaces to represent a number as a ratio. The numbers.Rational interface has two properties: numerator and denominator. float and Decimal do not support this interface, but they provide method as_integer_ratio() which return a 2-tuple (numerator, denominator). I propose to add math.as_integer_ratio() which unites both interfaces: uses the as_integer_ratio() method if it is defined, and uses the numerator and denominator properties otherwise. It will help in applications that work with exact numbers (e.g. modules fractions and statistics). ---------- components: Library (Lib) messages: 349390 nosy: mark.dickinson, rhettinger, serhiy.storchaka, stutzbach priority: normal severity: normal status: open title: Add math.as_integer_ratio() type: enhancement versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37822> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
