There is nothing to fix here. I suppose you agree that any comparison involving
NaNs is false, thus you first example is ok. The second one invokes undefined
behavior, because among the requirements of std::min is that the type T must be
LessThanComparable and when you instantiate std::min with a floating point T
including NaNs in its domain the '<' isn't irreflexive.
