-//! ## Argument types
-//!
-//! Each argument's type is dictated by the format string.
-//! There are various parameters which require a particular type, however.
-//! An example is the `{:.*}` syntax, which sets the number of decimal places

-//!
-//! ```
-//! let formatted_number = format!("{:.*}", 2, 1.234567);
-//!
-//! assert_eq!("1.23", formatted_number)
