New submission from STINNER Victor <vstin...@python.org>:
While debugging a GCC regression (*) on "HUGE_VAL * 0" used by Py_NAN macro, I noticed that Python can now C99 "NAN" constant. (*) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104389 In bpo-45440, I already removed legacy code for pre-C99 support and old platforms: "Building Python now requires a C99 <math.h> header file providing the following functions: copysign(), hypot(), isfinite(), isinf(), isnan(), round()." Attached patch modifies Py_NAN to simply reuse NAN. mathmodule.c and cmathmodule.c m_nan() still use _Py_dg_stdnan() by default (if PY_NO_SHORT_FLOAT_REPR is not defined). ---------- components: Interpreter Core messages: 412531 nosy: vstinner priority: normal severity: normal status: open title: Python can now use the C99 NAN constant versions: Python 3.11 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46640> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
