Hello,
The printing of Big_int is possible and AFAIK Big_int is an abstract
data type.
The following code is part of DebugPrinter.ml in VSYML [1]:
(** custom debug printer for big_int values (why is it missing in
vanilla ocaml?)
@param value_big_int the value to be printed
@return unit *)
let print_big_int (value_big_int:Big_int.big_int) =
Format.printf "%s" (Big_int.string_of_big_int value_big_int);;
And it is loaded by the following commands in the debugger:
load_printer build/debug/DebugPrinter.cmo
install_printer DebugPrinter.print_big_int
