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 funcGLib.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.
Converts a string to a floating point value.
