[Python-Dev] Re: Should we require IEEE 754 floating-point for CPython?

The consensus is to require IEEE 754 to build CPython, but not require it in the Python language specification. Updates (changed merged in bpo-46656): * Building Python 3.11 now requires a C11 compiler without optional C11 features. I wrote it in What's New in Python 3.11 and the PEP 7. * Building Python 3.11 now requires support for floating point Not-a-Number (NaN): remove the Py_NO_NAN macro. Victor
