## Concepts
|
|
|
|
```text
|
|
[<abstract>Dimension|
|
|
[base_dimension<Symbol, Unit>]<-[exp<Dimension, Num, Den>]
|
|
[derived_dimension<Child, Unit, Exponent...>]<-[exp<Dimension, Num, Den>]
|
|
[exp<Dimension, Num, Den>]<-[derived_dimension<Child, Unit, Exponent...>]
|
|
]
|
|
|
|
[<abstract>Quantity|
|
|
[quantity<Dimension, Unit, Rep>]
|
|
]
|
|
|
|
[<abstract>Unit]<-[Dimension]
|
|
[Dimension]<-[Quantity]
|
|
[Unit]<-[Quantity]
|
|
```
|
|
|
|
## Units
|
|
|
|
```text
|
|
#direction: right
|
|
|
|
[scaled_unit<Ratio, Unit>]<:-[unit<Child>]
|
|
[scaled_unit<Ratio, Unit>]<:-[named_unit<Child, Symbol, PrefixType>]
|
|
[scaled_unit<Ratio, Unit>]<:-[named_scaled_unit<Child, Symbol, PrefixType, Ratio, Unit>]
|
|
[scaled_unit<Ratio, Unit>]<:-[prefixed_unit<Child, Prefix, Unit>]
|
|
[scaled_unit<Ratio, Unit>]<:-[deduced_unit<Child, Dimension, Unit, Unit...>]
|
|
```
|
|
|
|
## Downcasting 1
|
|
|
|
```text
|
|
[detail::derived_dimension_base<exp<si::dim_length, 2>>]<:-[dim_area]
|
|
```
|
|
|
|
## Downcasting 2
|
|
|
|
```text
|
|
[downcast_base<detail::derived_dimension_base<exp<si::dim_length, 2>>>]<:-[detail::derived_dimension_base<exp<si::dim_length, 2>>]
|
|
[detail::derived_dimension_base<exp<si::dim_length, 2>>]<:-[downcast_child<dim_area, detail::derived_dimension_base<exp<si::dim_length, 2>>>]
|
|
[downcast_child<dim_area, detail::derived_dimension_base<exp<si::dim_length, 2>>>]<:-[dim_area]``` |
