func roundedUp() -> Self { … }
func roundedUp(withPrecision:Int) -> Self { … }
func roundedDown() -> Self { … }
func roundedDown(withPrecision:Int) -> Self { … }
Since the methods with implied precision of zero are equivalent to floor and
ceiling surely? I know floor and ceiling are pretty common terms, but they're
just a form rounding when it comes down to it.
