title: Extracting last two characters from a numeric string
body: <p>Okay. Say I have string</p>
  
  <pre><code>'193'
  </code></pre>
  
  <p>And I want to remove the last numbers and store them in an array so I can do operations with them. I know substr can delete the 2 characters, but I'm not sure how to store them after they've been removed..</p>
