| | | | | library numeric types (GH-6121)" (GH-22584) This reverts commit 58a7da9e125422323f79c4ee95ac5549989d8162.
* bpo-26680: Incorporate is_integer in all built-in and standard library ↵Robert Smallshire2020-10-011-1/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | numeric types (GH-6121) * bpo-26680: Adds support for int.is_integer() for compatibility with float.is_integer(). The int.is_integer() method always returns True. * bpo-26680: Adds a test to ensure that False.is_integer() and True.is_integer() are always True. * bpo-26680: Adds Real.is_integer() with a trivial implementation using conversion to int. This default implementation is intended to reduce the workload for subclass implementers. It is not robust in the presence of infinities or NaNs and may have suboptimal performance for other types. * bpo-26680: Adds Rational.is_integer which returns True if the denominator is one. This implementation assumes the Rational is represented in it's lowest form, as required by the class docstring. * bpo-26680: Adds Integral.is_integer which always returns True. * bpo-26680: Adds tests for Fraction.is_integer called as an instance method. The tests for the Rational abstract base class use an unbound method to sidestep the inability to directly instantiate Rational. These tests check that everything works correct as an instance method. * bpo-26680: Updates documentation for Real.is_integer and built-ins int and float. The call x.is_integer() is now listed in the table of operations which apply to all numeric types except complex, with a reference to the full documentation for Real.is_integer(). Mention of is_integer() has been removed from the section 'Additional Methods on Float'. The documentation for Real.is_integer() describes its purpose, and mentions that it should be overridden for performance reasons, or to handle special values like NaN. * bpo-26680: Adds Decimal.is_integer to the Python and C implementations. The C implementation of Decimal already implements and uses mpd_isinteger internally, we just expose the existing function to Python. The Python implementation uses internal conversion to integer using to_integral_value(). In both cases, the corresponding context methods are also implemented. Tests and documentation are included. * bpo-26680: Updates the ACKS file. * bpo-26680: NEWS entries for int, the numeric ABCs and Decimal. Co-authored-by: Robert Smallshire <rob@sixty-north.com>

* bpo-40792: Make the result of PyNumber_Index() always having exact type int. ↵Serhiy Storchaka2020-05-281-2/+2
| | | | | | | | | | | | (GH-20443) Previously, the result could have been an instance of a subclass of int. Also revert bpo-26202 and make attributes start, stop and step of the range object having exact type int. Add private function _PyNumber_Index() which preserves the old behavior of PyNumber_Index() for performance to use it in the conversion functions like PyLong_AsLong().
* bpo-37999: No longer use __int__ in implicit integer conversions. (GH-15636)Serhiy Storchaka2020-05-261-6/+1
| | | | Only __index__ should be used to make integer conversions lossless.
