You're probably best off to declare the inputs as integer not smallint.
Integer literals are assumed to be int4 by default, and since there's
no implicit downcast to int2 (anymore), writing a function this way will
require you to cast to smallint explicitly a lot. It's seldom worth
that notational hassle. You can cast inside the function if you really
need the values to be int2 inside it.
