The following functions
            are useful for performing various rounding calculations.
         
         NoteAlthough you can
               use these rounding functions as you would any other predefined function,
               they are actually implemented as user-defined functions in the functions
               file provided with the Flame installation. See 
                        Defining Your Own Functions.
