title: What is the meaning of i.to_s in Ruby?
body: <p>I want to understand a piece of code I found in Google:</p>
  
  <pre><code>i.to_s
  </code></pre>
  
  <p>In the above code <code>i</code> is an integer. As per my understanding <code>i</code> is being converted into a string. Is that true?</p>
