* gh-128770: raise warnings as errors in test suite - except for test_socket ↵Thomas Grainger2025-03-27
| | | | | which still logs warnings, and internal test warnings that are now logged (#128973) Co-authored-by: Bénédikt Tran <10796600+picnixz@users.noreply.github.com>
* gh-120010: Fix invalid (nan+nanj) results in _Py_c_prod() (GH-120287)Sergey B Kirpichev2024-12-06
| | | | | | | | | | | | | | | | | | | | In some cases, previously computed as (nan+nanj), we could recover meaningful component values in the result, see e.g. the C11, Annex G.5.1, routine _Cmultd(): >>> z = 1e300+1j >>> z*(nan+infj) # was (nan+nanj) (-inf+infj) That also fix some complex powers for small integer exponents, computed with optimized algorithm (by squaring): >>> z**5 # was (nan+nanj) Traceback (most recent call last): File "<python-input-1>", line 1, in <module> z**5 ~^^~ OverflowError: complex exponentiation
* gh-69639: Add mixed-mode rules for complex arithmetic (C-like) (GH-124829)Sergey B Kirpichev2024-11-26
| | | | | | | | | | | | | | | "Generally, mixed-mode arithmetic combining real and complex variables should be performed directly, not by first coercing the real to complex, lest the sign of zero be rendered uninformative; the same goes for combinations of pure imaginary quantities with complex variables." (c) Kahan, W: Branch cuts for complex elementary functions. This patch implements mixed-mode arithmetic rules, combining real and complex variables as specified by C standards since C99 (in particular, there is no special version for the true division with real lhs operand). Most C compilers implementing C99+ Annex G have only these special rules (without support for imaginary type, which is going to be deprecated in C2y).
* gh-113841: fix possible undefined division by 0 in _Py_c_pow() (GH-127211)Sergey B Kirpichev2024-11-23
| | | `x**y == 1/x**-y ` thus changing `/=` to `*=` by negating the exponent.
* gh-121039: add Floats/ComplexesAreIdenticalMixin to test.support.testcase ↵Sergey B Kirpichev2024-09-08
| | | | (GH-121071)
* gh-121905: Consistently use "floating-point" instead of "floating point" ↵Serhiy Storchaka2024-07-19
| | | | (GH-121907)
* gh-84978: Add float.from_number() and complex.from_number() (GH-26827)Serhiy Storchaka2024-07-15
| | | | | | They are alternate constructors which only accept numbers (including objects with special methods __float__, __complex__ and __index__), but not strings.
* gh-119372: Recover inf's and zeros in _Py_c_quot (GH-119457)Sergey B Kirpichev2024-06-29
| | | | | | In some cases, previously computed as (nan+nanj), we could recover meaningful component values in the result, see e.g. the C11, Annex G.5.2, routine _Cdivd().
* gh-109218: Deprecate weird cases in the complex() constructor (GH-119620)Serhiy Storchaka2024-05-30
| | | | | | | * Passing a string as the "real" keyword argument is now an error; it should only be passed as a single positional argument. * Passing a complex number as the "real" or "imag" argument is now deprecated; it should only be passed as a single positional argument.
* gh-109218: Refactor tests for the complex() constructor (GH-119635)Serhiy Storchaka2024-05-30
| | | | | | | | | | * Share common classes. * Use exactly representable floats and exact tests. * Check the sign of zero components. * Remove duplicated tests (mostly left after merging int and long). * Reorder tests in more consistent way. * Test more error messages. * Add tests for missed cases.
* gh-109802: Add coverage test for complex_abs() (GH-117449)Sergey B Kirpichev2024-04-04
| | | | | | | | * gh-109802: Add coverage test for complex_abs() This tests overflow on L594. // line numbers wrt to 0f2fa6150b
* gh-109802: Increase test coverage for complexobject.c (GH-112452)Sergey B Kirpichev2023-11-28

* gh-104263: Rely on Py_NAN and introduce Py_INFINITY (GH-104202)Sebastian Berg2023-05-10
| | | | | | | | | | This PR removes `_Py_dg_stdnan` and `_Py_dg_infinity` in favour of using the standard `NAN` and `INFINITY` macros provided by C99. This change has the side-effect of fixing a bug on MIPS where the hard-coded value used by `_Py_dg_stdnan` gave a signalling NaN rather than a quiet NaN. --------- Co-authored-by: Mark Dickinson <dickinsm@gmail.com>
* gh-99320: remove tests for old-style class from `test_complex` (#99321)Nikita Sobolev2022-11-10
|
* bpo-45229: Remove test_main in many tests (GH-28405)Serhiy Storchaka2021-09-19
| | | | | | | | | Instead of explicitly enumerate test classes for run_unittest() use the unittest ability to discover tests. This also makes these tests discoverable and runnable with unittest. load_tests() can be used for dynamic generating tests and adding doctests. setUpModule(), tearDownModule() and addModuleCleanup() can be used for running code before and after all module tests.
