>(So 'real' is same as 'double integer'.)

It certainly seems to be!

  (2 ^ 29) as double integer
  class of result
  --> real

  1 as double integer
  class of result
  --> real

But:

  1.5 as double integer
  --> 2.0

  2.5 as double integer
  --> 2.0

So. A nice, faster than 'round', IEEE-standard rounding process for
someone:

  (n as double integer) div 1

Though that's still not as fast as:

  if (n mod 2) ^ 2 > 0.25 then
    n div 0.5 - n div 1
  else
    n div 1
  end if
