Shouldn't Clip[Infinity] evaluate to 1? It remains unevaluated. I'm
trying to think of a reason why 1 wouldn't always be the correct
answer. Same with Clip[-Infinity], seems like it should be -1.

Hi,

what about

Clip[Infinity] // Simplify

?

Cheers
Patrick

You can fix by doing:

Unprotect[Clip];
Clip[x_List /; ! Developer`PackedArrayQ[x], a___] := Clip[#, a] & /@
x;
Clip[Infinity] = 1;
Clip[Infinity, ___, {_, max_}] := max;
Clip[-Infinity] = -1;
Clip[-Infinity, ___, {min_, _}] := min;
Protect[Clip];
