i think in your long post you have underlined among others: 1. in binary implementation of floats one bit was reserved to rounding; 2. this one bit is not enough to manage a correct rounding in a converted decimal base; my considerations: 3. someone i think had evaluated deciding rounding didn't worth more significative digits; 4. the only solution in general can be use more digits to manage rounding in decimal base, not only one but more (i should think better and experiment on how many); 5. the problem in general cannot be solved by an implementation of rounding but from a revision of the implementation of floats (i have solved pretty well my personal need but i'm speaking in general); 6. this is not really a weak impact i think, despite it's not impossible; 7. and last, i think the current implementation could derive from historical reasons when we worked on 8 bits machines, not 64 bits, and one bit was of worth, but i may be wrong. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41598> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
