[issue8947] Provide as_integer_ratio() method to Decimal

Mark Dickinson added the comment: After discussions on IRC, I'm going to close this as rejected. Convergence of the float and Decimal APIs is a nice idea, but in this case it's not clear that it really works. In particular, for duck typing to be sensible, int and Fraction would also have to

[issue8947] Provide as_integer_ratio() method to Decimal

Alexander Belopolsky added the comment: Raymond, conversion to Fraction does not really help in my use case of supporting timedelta * Decimal by duck typing. I can think of many other use cases where it will be helpful to accept either float or decimal without loss of precision. Is there a

[issue8947] Provide as_integer_ratio() method to Decimal

Raymond Hettinger added the comment: -0 I don't think we really need this (we've already got a reasonable conversion to Fraction). In general, we should have a aversion to adding any methods to the decimal API because it is already very fat. Adding more methods makes it harder to figure ou

[issue8947] Provide as_integer_ratio() method to Decimal

Alexander Belopolsky added the comment: Nice implementation. I wonder if the /5 loop can be eliminated by noting that /5 is *2 followed by decimal shift. (Probably not without fast decimal arithmetics.) A few documentation nits: 1. In Decimal methods there is no consistency in referring to

[issue8947] Provide as_integer_ratio() method to Decimal

Mark Dickinson added the comment: This seems like a reasonable request to me; I'd like to see a little bit of convergence between the float and Decimal APIs. One difference between the two types that's worth noting is that the float.as_integer_ratio() method can never take a ridiculous amoun

New submission from Alexander Belopolsky : Here is my use case: recently implemented timedelta * float operation starts with converting float to an int ratio. The same algorithm can be used for decimals, but they don't support as_integer_ratio(). -- components: Extension Modules messa
