    Gibt den größten möglichen Rundungsfehler in ULPs (Einheiten in der letzten Stelle) nach ISO 10967 definiert, die von 0,5 (Rundung auf die nächste Stelle) bis 1,0 (Rundung auf Null oder unendlich) variieren kann. Es ist nur sinnvoll, wenn std::numeric_limits<T>::is_integer == false .
    Original:
    Returns the largest possible rounding error in ULPs (units in the last place) as defined by ISO 10967, which can vary from 0.5 (rounding to the nearest digit) to 1.0 (rounding to zero or to infinity). It is only meaningful if std::numeric_limits<T>::is_integer == false.
