RE: C language binding of P1888 operations, especially min and max
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.
