# Abacus

Abacus is a module for transforming other modules into metric systems.

For example :

```elixir
defmodule Length do 
  use Abacus.SystemMetric
  unit :cm 
  unit :mm, (1/10)
  unit :dm, 10
  unit :m,  100
  unit :km, 100000
end

defmodule Money do 
  use Abacus.SystemMetric
  unit :euro
  unit :dollar, 1.06665
end
```

These modules make it possible to use functions to create values enclosed 
in a metric system and functions to manipulate these values.

For example : 

- [test/abacus_test.exs](https://github.com/xvw/abacus/blob/master/test/abacus_test.exs)
- [lib/abacus.ex](https://github.com/xvw/abacus/blob/master/lib/abacus.ex) (doctest comments)
