The lint "clippy::uninlined_format_args" recommends inline variables in format strings. Fix two places in the docs that do not do this. I noticed this because I copy/pasted one example in to my project, then noticed this lint error. This fixes:

error: variables can be used directly in the `format!` string
  --> src/main.rs:30:22
   |
30 |         let string = format!("{:.*}", decimals, magnitude);
   |                      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

error: variables can be used directly in the `format!` string
  --> src/main.rs:39:2
   |
39 |  write!(&mut io::stdout(), "{}", args).unwrap();

Hey! It looks like you've submitted a new PR for the library teams!

If this PR contains changes to any rust-lang/rust public library APIs then please comment with @rustbot label +T-libs-api -T-libs to tag it appropriately. If this PR contains changes to any unstable APIs please edit the PR description to add a link to the relevant API Change Proposal or create one if you haven't already. If you're unsure where your change falls no worries, just leave it as is and the reviewer will take a look and make a decision to forward on if necessary.

Examples of T-libs-api changes:

  • Stabilizing library features
  • Introducing insta-stable changes such as new implementations of existing stable traits on existing stable types
  • Introducing new or changing existing unstable library APIs (excluding permanently unstable features / features without a tracking issue)
  • Changing public documentation in ways that create new stability guarantees
  • Changing observable runtime behavior of library APIs

This is a very silly change. Feel free to reject it if this is not worth the effort. Thanks!
