      datatype using the type system and the built-in
      [`Numeric.new`](https://puppet.com/docs/puppet/latest/function.html#conversion-to-numeric),
      [`Integer.new`](https://puppet.com/docs/puppet/latest/function.html#conversion-to-integer), and
      [`Float.new`](https://puppet.com/docs/puppet/latest/function.html#conversion-to-float)
      function are used to convert to numeric values.
      ```
      notice(Integer(false)) # Notices 0
      notice(Float(true))    # Notices 1.0

    # We have real boolean values as well ...
    result = value ? 1 : 0
