402 * This function behaves like the standard strtod() function

404 * the current locale, since that would not be thread-safe.
405 * A limitation of the implementation is that this function
406 * will still accept localized versions of infinities and NANs.
408 * This function is typically used when reading configuration
409 * files or other non-user input that should be locale independent.
410 * To handle input from the user you should normally use the
411 * locale-sensitive system strtod() function.
413 * To convert from a #gdouble to a string in a locale-insensitive
414 * way, use g_ascii_dtostr().
416 * If the correct value would cause overflow, plus or minus %HUGE_VAL
417 * is returned (according to the sign of the value), and %ERANGE is
418 * stored in %errno. If the correct value would cause underflow,
419 * zero is returned and %ERANGE is stored in %errno.
421 * This function resets %errno before calling strtod() so that
422 * you can reliably detect overflow and underflow.
