That fits with my experience writing low level numeric code -- Integer can be a killer.
Inline machine operations v. out-of-line calls to an arbitrary precision integer C library: there shouldn't be any surprise here.
Obviously. However, what if 32 bit integers aren't sufficient? What perpetually puzzles me is that in C long long int has very good performance, *much* faster than gmp, in Haskell, on my computer, Int64 is hardly faster than Integer. So I stick to Integer mostly, it may be slow but it's correct. Cheers, Daniel
