[M3devel] quick question for the Modula-3 ether... LONGFLOAT??

Mon Apr 13 00:22:23 CEST 2009

It seems a bit more common a term than I would have thought from
someone's making a mistake.

I am talking about things like this.  In the stubgen sources, there are
two interfaces: Value.i3 and Type.i3.

Not the only place I've seen it in Modula-3.

Value.i3 has:

TYPE 
  T <: ROOT;
  (* Ordinal | Float | LongFloat | Extended | ArrayOrRecord | Set | 
     Text | Null *)

    Ordinal = T OBJECT ord: INTEGER END;
    (* ORD(the value) *)

    Float = T OBJECT val: REAL END;          (* XXX *)

    LongFloat = T OBJECT val: LONGREAL END;  (* XXX *)

    Extended  = T OBJECT val: EXTENDED END;

...

Type.i3 has:

TYPE
  T <: OBJECT name: Qid; visited := FALSE; brandsOK := TRUE  END;

  (* Ordinal | Real | LongReal | Extended | Reference  | Array 
  | Packed | Record | Set | Procedure  *)

  Ordinal =  T BRANDED OBJECT END; (* Enumeration | Subrange *)

  (* ... *)

  Real = T BRANDED OBJECT END;        (* YYY *)

  LongReal = T BRANDED OBJECT END;    (* YYY *)

  Extended = T BRANDED OBJECT END;

...

Is there a reason or is this just inconsistent crud from before the
glaciers came thru?
