Interesting thought. But a Integer div Integer cannot give a result
larger than a Integer type, so why is the compiler upscaling the result
it to a Int64?? If that is really what the compiler is doing, then
something is going way wrong, or I simply don't understand the logic.

I looked through the help, and the Objects.pp unit actually has a
LongDiv() method which does a DIV between two Integer types and returns
a Integer [as one would expect the result to be]. But looking at its
implementation I see it required a Integer cast too. Very strang
compiler behaviour. :-/

FUNCTION LongDiv (X: LongInt; Y: Integer): Integer;
BEGIN
  LongDiv := Integer(X DIV Y);
END;
