title: Display proper result of integers
body: <p>I have a code that shows the result in this form: example</p>
  
  <pre><code>  Amount:          10
    Total Amount:    200
    Tax:             30
    Net Balance:     2000
  </code></pre>
  
  <p>and my desire to show the result such as math type begin from right hand side and with 2 zero(00) after a decimal point. Example</p>
  
  <pre><code>  Amount:           10.00
    Total Amount:    200.00
    Tax:              30.00
    Net Balance:    2000.00
  </code></pre>
  
  <p>I am using double int for it, but really i don't know how to set the resulted amount begin from right side with an sequence and with a point and zeros.</p>
