; Note on the following tests with atan and inf.0:
;  The IEEE standard makes this decision. I think it's a bad one,
;  since (limit (atan (g x) (f x))) as x -> +inf.0 is not necessarily
;  (atan 1 1) when (limit (f x)) and (limit (g x)) are +inf.0.
;  Perhaps IEEE makes this choice because it's easiest to compute.
