Subject: can Ada give run-time error or warning for integer division with non-zero remainder?

In Ada when dividing 2 integers, the result is an integer
with the remainder ignored. Hence 3/2 gives 1
----------------------------------
with Ada.Integer_Text_IO ; use Ada.Integer_Text_IO ;
procedure foo4 is
N : constant integer := 3;
M : integer;
begin
M := N/2;
put(M);
end foo4;
--------------------------
>gnatmake foo4.adb
>./foo4
1
Now, suppose I want to know that a division between 2 integers
has resulted in nonzero remainder that was thrown away. May be
because my algorithm is meant to work only for even values and
an odd value means there was a bug somewhere and I want to
know about it.
Is there any kind of run-time switch to tell it to
check for this? I know I can always add logic myself to
check for this in the code, using rem() for example (which
might be the better solution actually) but I was just
wondering if there is a run-time switch for this.
thanks,
