Or, rather, an algorithm which achieves the Annex G treatment of NaNs and infinities but also takes more care to avoid undue overflow (an attachment to bug 18902 illustrates division with scaling to avoid overflow in calculation of either numerator or denominator, but without dealing with NaNs and infinities).
