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