This function behaves like the standard strtod() function
does in the C locale. It does this without actually changing
the current locale, since that would not be thread-safe.
A limitation of the implementation is that this function
will still accept localized versions of infinities and NANs.
This function is typically used when reading configuration
files or other non-user input that should be locale independent.
To handle input from the user you should normally use the
locale-sensitive system strtod() function.
To convert from a #gdouble to a string in a locale-insensitive
way, use g_ascii_dtostr().
If the correct value would cause overflow, plus or minus %HUGE_VAL
is returned (according to the sign of the value), and %ERANGE is
stored in %errno. If the correct value would cause underflow,
zero is returned and %ERANGE is stored in %errno.
This function resets %errno before calling strtod() so that
you can reliably detect overflow and underflow.
