The following functions provide locale-independent string to number conversions.
-.. cfunction:: double PyOS_ascii_strtod(const char *nptr, char **endptr)
-
- Convert a string to a :ctype:`double`. This function behaves like the Standard C
- function :cfunc:`strtod` does in the C locale. It does this without changing the
- current locale, since that would not be thread-safe.
-
- :cfunc:`PyOS_ascii_strtod` should typically be used for reading configuration
- files or other non-user input that should be locale independent.
-
- See the Unix man page :manpage:`strtod(2)` for details.
-
- .. deprecated:: 3.1
- Use :cfunc:`PyOS_string_to_double` instead.
-
-
.. cfunction:: double PyOS_string_to_double(const char *s, char **endptr, PyObject *overflow_exception)
Convert a string ``s`` to a :ctype:`double`, raising a Python
.. versionadded:: 3.1
-.. cfunction:: char* PyOS_ascii_formatd(char *buffer, size_t buf_len, const char *format, double d)
-
- Convert a :ctype:`double` to a string using the ``'.'`` as the decimal
- separator. *format* is a :cfunc:`printf`\ -style format string specifying the
- number format. Allowed conversion characters are ``'e'``, ``'E'``, ``'f'``,
- ``'F'``, ``'g'`` and ``'G'``.
-
- 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
.. versionadded:: 3.1
-.. cfunction:: double PyOS_ascii_atof(const char *nptr)
-
- Convert a string to a :ctype:`double` in a locale-independent way.
-
- See the Unix man page :manpage:`atof(2)` for details.
-
- .. deprecated:: 3.1
- Use :cfunc:`PyOS_string_to_double` instead.
-
-
.. cfunction:: char* PyOS_stricmp(char *s1, char *s2)
Case insensitive comparison of strings. The function works almost
