Converts a gdouble to a string, using the '.' as
decimal point. To format the number you pass in
a printf()-style format string. Allowed conversion
specifiers are 'e', 'E', 'f', 'F', 'g' and 'G'.
The returned buffer is guaranteed to be nul-terminated.
If you just want to want to serialize the value into a
string, use g_ascii_dtostr().
