------- Comment #2 from rguenth at gcc dot gnu dot org 2007-06-19 09:15 ------- Confirmed. For 2 NR steps to reach double precision (we'd miss it by some more ulps than the 2.5 for float precision) we would need to do at least the second NR in double precision. Note that this would make sense only for double precision input values that are exactly representable in float precision (otherwise, why the extra precision?). So practically not worth it.
