复数对象 ¶

Python’s complex number objects are implemented as two distinct types when viewed from the C API: one is the Python object exposed to Python programs, and the other is a C structure which represents the actual complex number value. The API provides functions for working with both.

作为 C 结构的复数 ¶

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. This is consistent throughout the API.

type Py_complex ¶

The C structure which corresponds to the value portion of a Python complex number object. Most of the functions for dealing with complex number objects use structures of this type as input or output values, as appropriate.

double real ¶

double imag ¶

The structure is defined as:

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