title: Rounding off values with greater number after dot
body: <p>I have this code which gives a result</p>
  
  <pre><code>double a = 128.73;
  double roundOff = Math.round(a*100)/100;
  System.out.println(roundOff);
  Result is :- 128.0
  </code></pre>
  
  <p>what I need that if the values after dot is greater than 5 i.e (6, 7, 8 or 9) then its
  should give result by adding 1 to the given value that has to be rounded off, i.e</p>
  
  <ul>
  <li>128.54 should give result to 128.0</li>
  <li>128.23 should give result to 128.0</li>
  <li>128.73 should give result to 129.0</li>
  <li>128.93 should give result to 129.0</li>
  </ul>
