GNAT Community 2020 (20200818-93): Big_Integer

["Frank Jørgen Jørgensen" <fjj@itema.no>]

Hi

I'm running the below program with GNAT Community 2020 (20200818-93)
on Windows 11 Home.
I have some problems trying to save big numbers to a file - so I noticed this behaviour:
If I open Test.dat in Visual Studio Hex editor,  it seems like this program saves this big number with a different bit pattern each time.
Is that as expected?
I do have some problems reading back the big numbers in my real code.
When I compile I get the warning: "Ada.Numerics.Big_Numbers.Big_Integers"  is an Ada 202x unit.

      F1 : File_Type;
      S1 : Stream_Access;
   begin
      B1 := 1;

      Ada.Streams.Stream_IO.Create (F1, Out_File, "Test.dat");
      S1 := Ada.Streams.Stream_IO.Stream (F1);
      Ada.Numerics.Big_Numbers.Big_Integers.Big_Integer'Write(S1, B1);
      Ada.Numerics.Big_Numbers.Big_Integers.Big_Integer'Output(S1, B1);
      Ada.Streams.Stream_IO.Close (F1);
end Test;
