quiz time, Ada fans:

consider

  declare
    x : integer;
    y : my_float := 1.5;
  begin
   x := integer(y);
  end;

What is the value of x?

	(a)	1
	(b)	2
	(c)	constraint_error is raised
	(d)	it depends





The right answer is (d), it depends.

	"4.6 (a)  

	   ... The conversion of a real value to an integer type rounds
	to the nearest integer; if the operand is halfway between two
	integers (within the accuracy of the real subtype), rounding may
	be either up or down.

	"

So the implementor can pick how he wants to round.  This strikes me as 
a portability bug, but, on the other hand, I don't have a lot of sympathy
for people who depend on these kinds of type conversion....
