| 38 -- * Dimensioned type | |
| 39 | |
| 40 -- 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 => ( | |
| 46 -- (Unit_Name => Meter, Unit_Symbol => 'm', Dim_Symbol => 'L'), | |
| 47 -- (Unit_Name => Kilogram, Unit_Symbol => "kg", Dim_Symbol => 'M'), | |
| 48 -- (Unit_Name => Second, Unit_Symbol => 's', Dim_Symbol => 'T'), | |
| 49 -- (Unit_Name => Ampere, Unit_Symbol => 'A', Dim_Symbol => 'I'), | |
| 50 -- (Unit_Name => Kelvin, Unit_Symbol => 'K', Dim_Symbol => "Θ"), | |
| 51 -- (Unit_Name => Mole, Unit_Symbol => "mol", Dim_Symbol => 'N'), | |
| 52 -- (Unit_Name => Candela, Unit_Symbol => "cd", Dim_Symbol => 'J')); | |
| 53 | |
| 54 -- * Dimensioned subtype | |
| 55 | |
| 56 -- A dimensioned subtype is a subtype directly defined from the dimensioned | |
| 57 -- type and to which the aspect Dimension applies to. | |
| 58 | |
| 59 -- subtype Length is Mks_Type | |
| 60 -- with | |
| 61 -- Dimension => (Symbol => 'm', | |
| 62 -- Meter => 1, | |
| 63 -- others => 0); | |
