-    /// ### What it does
-    /// Checks for division of integers
-    ///
-    /// ### Why is this bad?
-    /// When outside of some very specific algorithms,
-    /// integer division is very often a mistake because it discards the
-    /// remainder.
-    ///
-    /// ### Example
-    /// ```rust
-    /// let x = 3 / 2;
-    /// println!("{}", x);
-    /// ```
-    ///
-    /// Use instead:
-    /// ```rust
-    /// let x = 3f32 / 2f32;
-    /// println!("{}", x);
-    /// ```
