PROCEDURE Frac (r: REAL) : REAL ;


(*
   Int - returns the integer part of r. It rounds the value towards zero.
*)

PROCEDURE Int (r: REAL) : INTEGER ;


(*
   Round - returns the number rounded to the nearest integer.
*)

PROCEDURE Round (r: REAL) : INTEGER ;


(*
   Float - returns a REAL value corresponding to, i.
*)

PROCEDURE Float (i: INTEGER) : REAL ;


(*
   Trunc - round to the nearest integer not larger in absolute
           value.
*)

PROCEDURE Trunc (r: REAL) : INTEGER ;


(*
   Fracl - returns the fractional component of, r.
*)

PROCEDURE Fracl (r: LONGREAL) : LONGREAL ;


(*
   Intl - returns the integer part of r. It rounds the value towards zero.
