#2994: min() and max() are problematic in AutoDiff. We have used max(a,b) = (a+b + abs(b-a)) / 2 but this is problematic because of catastrophic cancellation. Min() and Max() are necessary for interval calculation. However, there we only need to determine min and max for double values (or duals). We do not need min() and max() in general.
