Why? There are clear advantages to floating point arithmetic done in base 2 (speed, minimum possible rounding error, least amount of wobble), and a different advantage to floating point done in base 10 (matches exactly the standard decimal notation used by humans with no conversion error), Outside of those two bases, arithmetic done in any other base is going to combine the worst of both: - slower; - larger errors when converting from decimal numbers (in general); - larger rounding errors; - larger wobble; with no corresponding advantages unless your data is coming to you in arbitrary bases. Doing floating point arithmetic in decimal is already slower and less accurate than doing it in binary. I'd like to hear more about your use-case for doing it in base 19 or base 7, say, but I would have to guess that it is likely to be such a niche use-case that this functionality doesn't belong in the standard library. -- Steve _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
