title: How do I print in Rust the type of a variable?
body: <p>I have the following:</p>
  
  <pre><code>let mut my_number = 32.90;
  </code></pre>
  
  <p>How do I print the type of <code>my_number</code>?</p>
  
  <p>Using <code>type</code> and <code>type_of</code> did not work. Is there another way I can print the number's type?</p>
