Which brings me to a question: is there a better way to write -inf and +inf in Haskell than "-1/0" and "1/0"?
Why not do it with types:
data InfDbl = Dbl Double | PositiveInfinity | NegativeInfinity
? Double already has +Inf and -Inf; it's just that Haskell doesn't have (AFAIK) syntax to write them as constants. --KW 8-) -- Keith Wansbrough <kw217@cl.cam.ac.uk> http://www.cl.cam.ac.uk/users/kw217/ University of Cambridge Computer Laboratory.
