Hi,

suppose I use the following code for=20 fact

let rec fact n =3D if n <=3D 1 then = 1 else n * fact=20 (n - 1) ;;

Because an integer number is = represented by a fixed=20 number of bytes I will get a runtime overflow if n is chosen too=20 large.

Is there in Ocamel a workaround to cope = with this=20 problem . Something like " Onoverflow goto .. " in imperative=20 languages.

Thx

Scott
