Samuel Iseli <samuel.is...@gmail.com> added the comment: I would definitely classify this as a bug in Python 2.7 as it breaks backwards-compatibility for embedding environments that default to 64bit FPU precision (e.g. Delphi).
Additionally the bug is very hard to detect and leads to wrong values with possibly disastrous effects. Appended a patch with a new implementation of the Py_SET_53BIT_PRECISION_* macros for win32: - precision is set only when needed - setting and restoring only the x87 controlword (using __control87_2 function). - macros are not used for WIN64 as there's no x87 there - there's no need for a custom symbol in the vc project anymore, as I'm using the predefined _WIN32 symbol. ---------- Added file: http://bugs.python.org/file24408/74745.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13889> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
