title: How to insert a character in a string at a certain position?
body: <p>I'm getting in an <code>int</code> with a 6 digit value. I want to display it as a <code>String</code> with a decimal point (.) at 2 digits from the end of <code>int</code>. I wanted to use a <code>float</code> but was suggested to use <code>String</code> for a better display output (instead of <code>1234.5</code> will be <code>1234.50</code>). Therefore, I need a function that will take an <code>int</code> as parameter and return the properly formatted <code>String</code> with a decimal point 2 digits from the end.</p>
  
  <p>Say:</p>
  
  <pre><code>int j= 123456 
  Integer.toString(j); 
  
  //processing...
  
  //output : 1234.56
  </code></pre>
