All -- Put routines are modelled after those in package Ada.Text_IO.Integer_IO -- with the addition of an extra default parameter. -- All the examples in this package are based on the MKS system of units: -- type Mks_Type is new Integer -- with -- Dimension_System => ((Meter, 'm'), -- (Kilogram, "kg"), -- (Second, 's'), -- (Ampere, 'A'), -- (Kelvin, 'K'), -- (Mole, "mol"), -- (Candela, "cd")); -- Parameter Symbol may be used in the following manner: -- Case 1. A value is supplied for Symbol -- The string appears as a suffix of Item -- Obj : Mks_Type := 2; -- Put (Obj, Symbols => " dimensionless"); -- The corresponding output is: 2 dimensionless -- Case 2. No value is supplied for Symbol and Item is dimensionless -- Item appears without a suffix -- Obj : Mks_Type := 2; -- Put (Obj); -- The corresponding output is: 2 -- 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; -- Put (Obj); -- The corresponding output is: 2 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 => 2, -- others => 0); -- Obj : Random := 5; -- Put (Obj); -- The corresponding output is: 5 m**3.cd**2 with Ada.Text_IO; use Ada.Text_IO; generic type Num_Dim_Integer is range <>; package System.Dim.Integer_IO is Default_Width : Field := Num_Dim_Integer'Width; Default_Base : Number_Base := 10; procedure Put (File : File_Type; Item : Num_Dim_Integer; Width : Field := Default_Width; Base : Number_Base := Default_Base; Symbols : String := ""); procedure Put (Item : Num_Dim_Integer; Width : Field := Default_Width; Base : Number_Base := Default_Base; Symbols : String := ""); procedure Put (To : out String; Item : Num_Dim_Integer; Base : Number_Base := Default_Base; Symbols : String := ""); pragma Inline (Put); end System.Dim.Integer_IO;
