Writing that is never a big deal. Forgetting to write that when you need to incurs immediate loss of precision, which is a big deal in applications where it matters at all. Knuth (Seminumerical Algorithms) discusses "slash" arithmetic (including floating slash), ie, fixed width fractional arithmetic (floating slash assigns a varying division of bits to numerator and denominator to get the closest representable number). I wonder if a slash type which either converts to float on need for rounding (or converts to float on under/overflow of numerator or denominator) might be workable. _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/I37PZRQS5UID5SWSSYMDOANRNYW2O3SL/ Code of Conduct: http://python.org/psf/codeofconduct/
