-- This package provides output routines for float dimensioned types. All Put
-- routines are modelled after those in package Ada.Text_IO.Float_IO with the
-- addition of an extra default parameter.
-- Parameter Symbol may be used in the following manner (all the examples are
-- based on the MKS system of units as defined in package System.Dim.Mks):
-- Case 1. A value is supplied for Symbol
-- The string appears as a suffix of Item
-- Obj : Mks_Type := 2.6;
-- Put (Obj, 1, 1, 0, " dimensionless");
-- The corresponding output is: 2.6 dimensionless
-- Case 2. No value is supplied for Symbol and Item is dimensionless
-- Item appears without a suffix
-- Obj : Mks_Type := 2.6;
-- Put (Obj, 1, 1, 0);
-- The corresponding output is: 2.6
-- Case 3. No value is supplied for Symbol and Item has a dimension
-- If the type of Item is a dimensioned subtype whose symbolic name is not
-- empty, then the symbolic name appears as a suffix.
-- subtype Length is Mks_Type
-- with
-- Dimension => ('m',
-- Meter => 1,
-- others => 0);
-- Obj : Length := 2.3 * dm;
-- Put (Obj, 1, 2, 0);
-- The corresponding output is: 0.23 m
-- Otherwise, a new string is created and appears as a suffix of Item.
-- This string results in the successive concatanations between each
-- dimension symbolic name raised by its corresponding dimension power from
-- the dimensions of Item.
-- subtype Random is Mks_Type
-- with
-- Dimension => ("",
-- Meter => 3,
-- Candela => -1,
-- others => 0);
-- Obj : Random := 5.0;
-- Put (Obj);
-- The corresponding output is: 5.0 m**3.cd**(-1)
-- Put (3.3 * km * dm * min, 5, 1, 0);
-- The corresponding output is: 19800.0 m**2.s
