9/// A meta trait for arithmetic.
10///
11/// Arithmetic types do all the usual stuff you'd expect numbers to do. They are
12/// guaranteed to be able to represent at least `u32` values without loss, hence
13/// the trait implies `From<u32>` and smaller ints. All other conversions are
14/// fallible.
