* bpo-9009 discussed maintenance of Python/dtoa.c * Python/dtoa.c asks to frequently update it from "upstream" http://www.netlib.org/fp/dtoa.c * The upstream is also mentioned in the license: https://docs.python.org/dev/license.html#strtod-and-dtoa ... in practice, it seems like Python became the "upstream". I see lot of changes, but I'm not sure that version maintained by David M. Gay on http://www.netlib.org/fp/dtoa.c has been updated since Mark Dickinson copied it to Python/dtoa.c: commit b08a53a99def3fa949643974f713b5b189e21bc7 Author: Mark Dickinson <dicki...@gmail.com> Date: Thu Apr 16 19:52:09 2009 +0000 Issue #1580: use short float repr where possible. - incorporate and adapt David Gay's dtoa and strtod into the Python core - on platforms where we can use Gay's code (almost all!), repr(float) is based on the shortest sequence of decimal digits that rounds correctly. - add sys.float_repr_style attribute to indicate whether we're using Gay's code or not - add autoconf magic to detect and enable SSE2 instructions on x86/gcc - slight change to repr and str: repr switches to exponential notation at 1e16 instead of 1e17, str switches at 1e11 instead of 1e12 ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36262> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
