It doesn't matter if the value is a tiny bit below or above the
desired number the following function will always round it to
the nearest integer... I think. This is untested so I may have
some syntax errors but I think the logic is sound. Please let
me know if it isn't. Please note also that my problem is now
solved, thanks to you and others.

function int_round (atom a)
  integer sign sign = 1
  if a < 0 then
    sign = -1
  end if
  return floor (a + .5 * sign)
end function

I suppose one could write a recursive version of this to
work with sequences.

later,
