@Returns: the same pointer passed in as @string.
<!-- ##### FUNCTION g_strtod ##### -->
<!-- ##### MACRO G_ASCII_DTOSTR_BUF_SIZE ##### -->
<para>
Converts a string to a gdouble value.
It calls the standard <function>strtod()</function> function
to handle the conversion, but if the string is not completely converted
it attempts the conversion again in the "C" locale, and returns the best
match.
A good size for a buffer to be passed into <function>g_ascii_dtostr</function>.
It is guaranteed to be enough for all output of that function on systems with
64bit IEEE compatible doubles.

<para>
The typical usage would be something like:

char buf[G_ASCII_DTOSTR_BUF_SIZE];
fprintf (out, "value=%s\n", g_ascii_dtostr (buf, sizeof (buf), value));
</literal>

in the conversion.
