rustdoc: Add an example for round that is different from truncate

The current examples for [round](https://github.com/rust-lang/rust/blob/master/library/std/src/f64.rs#L75) would have the same results as the example for [truncate](https://github.com/rust-lang/rust/blob/master/library/std/src/f64.rs#L95).  This PR adds one more example to `round` that will have a different result from `truncate`.
