So converting > big_int into C seems possible to me. It seems you should have a look at the numerix library or at the OCaml binding for GMP. I never used any of them so I cannot guaranty there are really working (there are not a lot of references to them) but I think they are more likely to be usable on both OCaml and C side.Jianzhou Zhao then asked and Olivier Schwander replied:

Yes, there is also mlgmpidl http://www.inrialpes.fr/pop-art/people/bjeannet/mlxxxidl-forge/mlgmpidl/.

The Journal of Functional Programming publishes book reviews. I have just updated: list of books for review in the journal of functional programming, available here: http://www.cs.kent.ac.uk/people/staff/sjt/JFP/available.html which also has a link to a set of review guidelines. If you review a book you get a free copy (in some cases of an e-book): the typical deadline for a review is three months.
Thanks to Alp Mestan, we now include in the Caml Weekly News the links to the recent posts from the ocamlcore planet blog at http://planet.ocamlcore.org/.
