title: Differences of float in python2 and python3?
body: <p>I wrote those simple lines and run them on python 2/3.</p>
  
  <pre><code>i=1.194857193845710948754654
  print(len(str(i)))
  </code></pre>
  
  <p>I got 2 different outputs. What is the reason for that? and how could I achieve the same output in python2 ?</p>
  
  <p>Output python2:</p>
  
  <pre><code>&gt;&gt;&gt; 13
  </code></pre>
  
  <p>Output python3:</p>
  
  <pre><code>&gt;&gt;&gt; 18
  </code></pre>
