The compiler doesn't need extra specification but an unbiased reader of
your source would appreciate it.
For myself I always use the short form for integer (or ranges of it) only.
So I would prefer
Put_Line ("Iteration" & Num &
" Result:" & Result &
" Time:" & Duration'Image(Elapsed_Time));
If it is inevitable that the type of Elapsed_Time may change in future then
it could be good idea to define a subtype:
subtype My_Duration is Duration;
Put_Line ("Iteration" & Num &
" Result:" & Result &
" Time:" & My_Duration'Image(Elapsed_Time));
If you have to change the type you just need to change one line (hopefully).
Regards,
Ingo
