New submission from STINNER Victor <vstin...@python.org>:
It has been decided to require IEEE 754 to build Python 3.11: https://mail.python.org/archives/list/python-...@python.org/thread/J5FSP6J4EITPY5C2UJI7HSL2GQCTCUWN/ At Python startup, _PyFloat_InitState() checks the IEEE 754 format at runtime. It can be changed using float.__get_format__() and float.__set_format__() methods. These methods docstrings say that they only exist to test Python itself: "You probably don't want to use this function. It exists mainly to be used in Python's test suite." These methods are private and not documented. I propose to remove them. Once they will be removed, it will become possible to move the detection of the IEEE 754 format in the build step (./configure script) rather than doing the detection at runtime (slower). It would remove an "if" in _PyFloat_Pack4() and _PyFloat_Pack8(), and allow to specialize these functions for the detected format at build time. These functions are used by serialization formats: marshal, pickle and struct. ---------- components: Interpreter Core messages: 413943 nosy: vstinner priority: normal severity: normal status: open title: Remove float.__get_format__() and float.__set_format__() versions: Python 3.11 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46852> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
