--    A dimensioned type is a type (more accurately a first subtype) to which
41
--    the aspect Dimension_System applies to.
42
 
43
--      type Mks_Type is new Long_Long_Float
44
--        with
45
--         Dimension_System => ((Meter, 'm'),
46
--           (Kilogram, "kg"),
47
--           (Second,   's'),
48
--           (Ampere,   'A'),
49
--           (Kelvin,   'K'),
50
--           (Mole,     "mol"),
51
--           (Candela,  "cd"));
52
 
53
--      'm' is the symbolic name of dimension Meter
54
 
55
--  * Dimensioned subtype
56
 
57
--    A dimensioned subtype is a subtype directly defined from the dimensioned
58
--    type and to which the aspect Dimension applies to.
59
 
60
--      subtype Length is Mks_Type
61
--        with
62
--         Dimension => ('m',
63
--           Meter =>  1,
64
--           others => 0);
