@ -73,6 +73,43 @@ The following functions provide locale-independent string to number conversions.
The return value is a pointer to *buffer* with the converted string or NULL if
the conversion failed.
.. deprecated:: 3.1
Use :cfunc:`PyOS_double_to_string` instead.
.. cfunction:: char* PyOS_double_to_string(double val, char format_code, int precision, int flags, int *ptype)
Convert a :ctype:`double` *val* to a string using supplied
*format_code*, *precision*, and *flags*.
*format_code* must be one of ``'e'``, ``'E'``, ``'f'``, ``'F'``, ``'g'``,
``'G'``, ``'s'``, or ``'r'``. For ``'s'`` and ``'r'``, the supplied
*precision* must be 0 and is ignored. These specify the standard
:func:`str` and :func:`repr` formats, respectively.
*flags* can be zero or more of the values *Py_DTSF_SIGN*,
*Py_DTSF_ADD_DOT_0*, or *Py_DTSF_ALT*, or-ed together:
* *Py_DTSF_SIGN* means to always precede the returned string with a sign
character, even if *val* is non-negative.
* *Py_DTSF_ADD_DOT_0* means to ensure that the returned string will not look
like an integer.
* *Py_DTSF_ALT* means to apply "alternate" formatting rules. See the
documentation for the :cfunc:`PyOS_snprintf` ``'#'`` specifier for
details.
If *ptype* is non-NULL, then the value it points to will be set to one of
*Py_DTST_FINITE*, *Py_DTST_INFINITE*, or *Py_DTST_NAN*, signifying that
*val* is a finite number, an infinite number, or not a number, respectively.
The return value is a pointer to *buffer* with the converted string or
*NULL* if the conversion failed. The caller is responsible for freeing the
returned string by calling :cfunc:`PyMem_Free`.
.. versionadded:: 3.1
.. cfunction:: double PyOS_ascii_atof(const char *nptr)
