Yes, indeed. I've been viewing "max" and "min" exactly as Vladik
stated, as natural extensions of the point functions, not to be
confused with "mag" and "mig". I've found both concepts to
be of use in practice.

In line with all other operations of interval arithmetic, a natural
idea for max(A,B) for two intervals A and B should be the set of all
possible values max(a,b) when a is in A and b is in B. In this case,
max([al,au],[bl,bu]) = [max(al,bl),max(au,bu)]. An example of A =
[0,2] and B = [1,1] for which we get max(A,B) = [1,2], shows that
this can be neither A not B

I would expect that if a,b are intervals, that the return value of
max(a,b) is either the memory location where a is stored or where b
is stored. Not another location where there is a conversion of a or
b to the type of x. But frankly I don't know what is intended here.
