* [3.11] gh-109546: Add more tests for formatting floats (GH-109548) (#109685)Victor Stinner2023-09-211-2/+7
| | | | | | | gh-109546: Add more tests for formatting floats (GH-109548) (cherry picked from commit beb5ec5817b645562ebbdd59f25683a93061c32c) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
* gh-95605: Fix `float(s)` error message when `s` contains only whitespace ↵Miss Islington (bot)2022-08-111-0/+4
| | | | | | | | (GH-95665) (GH-95858) This PR fixes the error message from float(s) in the case where s contains only whitespace. (cherry picked from commit 97e9cfa75a80b54a0630b7371f35e368a12749d1) Co-authored-by: Mark Dickinson <dickinsm@gmail.com>

* bpo-45995: add "z" format specifer to coerce negative 0 to zero (GH-30049)John Belmonte2022-04-111-12/+10
| | | | | | | | Add "z" format specifier to coerce negative 0 to zero. See https://github.com/python/cpython/issues/90153 (originally https://bugs.python.org/issue45995) for discussion. This covers `str.format()` and f-strings. Old-style string interpolation is not supported. Co-authored-by: Mark Dickinson <dickinsm@gmail.com>
* bpo-46906: Add PyFloat_Pack8() to the C API (GH-31657)Victor Stinner2022-03-111-1/+73
| | | | | | | | | | | | | | | | | | | | | | Add new functions to pack and unpack C double (serialize and deserialize): * PyFloat_Pack2(), PyFloat_Pack4(), PyFloat_Pack8() * PyFloat_Unpack2(), PyFloat_Unpack4(), PyFloat_Unpack8() Document these functions and add unit tests. Rename private functions and move them from the internal C API to the public C API: * _PyFloat_Pack2() => PyFloat_Pack2() * _PyFloat_Pack4() => PyFloat_Pack4() * _PyFloat_Pack8() => PyFloat_Pack8() * _PyFloat_Unpack2() => PyFloat_Unpack2() * _PyFloat_Unpack4() => PyFloat_Unpack4() * _PyFloat_Unpack8() => PyFloat_Unpack8() Replace the "unsigned char*" type with "char*" which is more common and easy to use.

* bpo-46852: Remove the float.__set_format__() method (GH-31585)Victor Stinner2022-02-251-70/+0
| | | | | | Remove the undocumented private float.__set_format__() method, previously known as float.__set_format__() in Python 3.7. Its docstring said: "You probably don't want to use this function. It exists mainly to be used in Python's test suite."
* bpo-45668: Fix PGO tests without test extensions (GH-29315)Christian Heimes2021-11-011-1/+2

* bpo-43413: Fix handling keyword arguments in subclasses of some buitin ↵Serhiy Storchaka2021-09-121-0/+27
| | | | | | | | classes (GH-26456) * Constructors of subclasses of some buitin classes (e.g. tuple, list, frozenset) no longer accept arbitrary keyword arguments. * Subclass of set can now define a __new__() method with additional keyword parameters without overriding also __init__().

* bpo-35560: Remove assertion from format(float, "n") (GH-11288)Xtreak2019-01-071-0/+19
| | | | | Fix an assertion error in format() in debug build for floating point formatting with "n" format, zero padding and small width. Release build is not impacted. Patch by Karthikeyan Singaravelan.
* bpo-34087: Fix buffer overflow in int(s) and similar functions (GH-8274)INADA Naoki2018-07-141-0/+3
| | | | | | `_PyUnicode_TransformDecimalAndSpaceToASCII()` missed trailing NUL char. It caused buffer overflow in `_Py_string_to_number_with_underscores()`. This bug is introduced in 9b6c60cb.
* bpo-31979: Simplify transforming decimals to ASCII (#4336)Serhiy Storchaka2017-11-131-1/+1
| | | | | in int(), float() and complex() parsers. This also speeds up parsing non-ASCII numbers by around 20%.
* bpo-31373: remove overly strict float range checks (#3486)Benjamin Peterson2017-09-111-0/+6
| | | | | This undoes a853a8ba7850381d49b284295dd6f0dc491dbe44 except for the pytime.c parts. We want to continue to allow IEEE 754 doubles larger than FLT_MAX to be rounded into finite floats. Tests were added to very this behavior.

* Issue #26983: float() now always return an instance of exact float.Serhiy Storchaka2016-06-031-8/+13
| | | | | | The deprecation warning is emitted if __float__ returns an instance of a strict subclass of float. In a future versions of Python this can be an error.

| | | | | | | | | | | | | | | | This avoids possible buffer overreads when int(), float(), compile(), exec() and eval() are passed bytes-like objects. Similar code is removed from the complex() constructor, where it was not reachable. Patch by John Leitch, Serhiy Storchaka and Martin Panter.
