What are the minimum/maximum integers in gprolog?

Question

What are the minimum/maximum integers in gprolog? Is there a way to reference these numbers without using a "magic number"?

Answer 1

I think these should work:

current_prolog_flag(bounded, X).
current_prolog_flag(min_integer, Y).
current_prolog_flag(max_integer, Z).

bounded tells you whether your implementation supports arbitrary large integers; if it's false, the min_integer / max_integer calls will fail.
