Objetos de números complejos

type PyComplexObject

Este subtipo de PyObject representa un objeto de número complejo de Python.

Py_complex cval

The complex number value, using the C Py_complex representation.

Deprecated since version 3.15.0a0 (unreleased), will be removed in version 3.20: Use PyComplex_AsCComplex() and PyComplex_FromCComplex() to convert a Python complex number to/from the C Py_complex representation.

PyTypeObject PyComplex_Type

Part of the Stable ABI.

Esta instancia de PyTypeObject representa el tipo de número complejo de Python. Es el mismo objeto que complex en la capa de Python.

int PyComplex_Check(PyObject *p)

Retorna verdadero si su argumento es un PyComplexObject o un subtipo de PyComplexObject. Esta función siempre finaliza con éxito.

int PyComplex_CheckExact(PyObject *p)

Retorna verdadero si su argumento es un PyComplexObject, pero no un subtipo de PyComplexObject. Esta función siempre finaliza con éxito.

PyObject *PyComplex_FromDoubles(double real, double imag)

Return value: New reference. Part of the Stable ABI.

Return a new PyComplexObject object from real and imag. Return NULL with an exception set on error.

double PyComplex_RealAsDouble(PyObject *op)

Part of the Stable ABI.

Return the real part of op as a C double.

If op is not a Python complex number object but has a __complex__() method, this method will first be called to convert op to a Python complex number object. If __complex__() is not defined then it falls back to call PyFloat_AsDouble() and returns its result.

Upon failure, this method returns -1.0 with an exception set, so one should call PyErr_Occurred() to check for errors.

Distinto en la versión 3.13: Use __complex__() if available.

double PyComplex_ImagAsDouble(PyObject *op)

Part of the Stable ABI.

Return the imaginary part of op as a C double.

If op is not a Python complex number object but has a __complex__() method, this method will first be called to convert op to a Python complex number object. If __complex__() is not defined then it falls back to call PyFloat_AsDouble() and returns 0.0 on success.

Upon failure, this method returns -1.0 with an exception set, so one should call PyErr_Occurred() to check for errors.

Distinto en la versión 3.13: Use __complex__() if available.

type Py_complex

This C structure defines export format for a Python complex number object.

double real

double imag

The structure is defined as:

typedef struct {
    double real;
    double imag;
} Py_complex;

PyObject *PyComplex_FromCComplex(Py_complex v)

Return value: New reference.

Create a new Python complex number object from a C Py_complex value. Return NULL with an exception set on error.

Py_complex PyComplex_AsCComplex(PyObject *op)

Retorna el valor Py_complex del número complejo op.

If op is not a Python complex number object but has a __complex__() method, this method will first be called to convert op to a Python complex number object. If __complex__() is not defined then it falls back to __float__(). If __float__() is not defined then it falls back to __index__().

Upon failure, this method returns Py_complex with real set to -1.0 and with an exception set, so one should call PyErr_Occurred() to check for errors.

Distinto en la versión 3.8: Use __index__() if available.

Números complejos como estructuras C

The API also provides functions for working with complex numbers, using the Py_complex representation. Note that the functions which accept these structures as parameters and return them as results do so by value rather than dereferencing them through pointers.

Please note, that these functions are soft deprecated since Python 3.15. Avoid using this API in a new code to do complex arithmetic: either use the Number Protocol API or use native complex types, like double complex.

Py_complex _Py_c_sum(Py_complex left, Py_complex right)

Retorna la suma de dos números complejos, utilizando la representación C Py_complex.

Obsoleto desde la versión 3.15.

Py_complex _Py_c_diff(Py_complex left, Py_complex right)

Retorna la diferencia entre dos números complejos, usando la representación C Py_complex.

Obsoleto desde la versión 3.15.

Py_complex _Py_c_neg(Py_complex num)

Retorna la negación del número complejo num, utilizando la representación C Py_complex.

Obsoleto desde la versión 3.15.

Py_complex _Py_c_prod(Py_complex left, Py_complex right)

Retorna el producto de dos números complejos, usando la representación C Py_complex.

Obsoleto desde la versión 3.15.

Py_complex _Py_c_quot(Py_complex dividend, Py_complex divisor)

Retorna el cociente de dos números complejos, utilizando la representación C Py_complex.

If divisor is null, this method returns zero and sets errno to EDOM.

Obsoleto desde la versión 3.15.

Py_complex _Py_c_pow(Py_complex num, Py_complex exp)

Retorna la exponenciación de num por exp, utilizando la representación C Py_complex.

If num is null and exp is not a positive real number, this method returns zero and sets errno to EDOM.

Set errno to ERANGE on overflows.

Obsoleto desde la versión 3.15.

double _Py_c_abs(Py_complex num)

Return the absolute value of the complex number num.

Set errno to ERANGE on overflows.

Obsoleto desde la versión 3.15.
