I am not sure if this is a reasonable question. Does OCaml already
have functions that do convertion between arbitrary-precision integers
big_int in OCaml and any representation of large intergers in C? The
implementation of big_int (otherlibs/num/big_int.*) uses nat
(otherlibs/num/nat.*). Nat is a customized allocation (in C) as a list
of native integers to represent arbitrary-precision. 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.
Thanks. Are they the MLGMP and Numerix listed in "the Caml Hump:
General purpose libraries :: Numeric computation" ?
