title: RoundingMode HALF_UP is not working properly
body: <p>From my understand, RoundingMode.HALF_UP uses our tradition style of rounding. However, it is not giving me the desired results:</p>
  
  <p>I'm using DecimalFormat() with different parameters(#, #.#, ... etc) and inputting the double 3.5545</p>
  
  <pre><code>// taken from Util    
  public static void setRound(int a)      // Set rounding decimal places
  {
      roundTo = a;
  
      String t = "#";
      if (roundTo &gt; 0)
      {
          t += ".";
          for (int u = 1; u &lt;= roundTo; u++)
              t += "#";
      }
  
      df = new DecimalFormat(t);
      df.setRoundingMode(RoundingMode.HALF_UP);
  }
  
  public static String round(double d)    // Rounds up answers to set place
  {
      return df.format(d);
  }
  
  // taken from Testing class
   for (int a = 0; a &lt; 5; a++)
      {
      Util.setRound(a);
      System.out.println(Util.round(3.5545));
      }
  
  // results
  0 -&gt; 4              
  1 -&gt; 3.6   
  2 -&gt; 3.55   
  3 -&gt; 3.554 *(I want 3.555)*  
  4 -&gt; 3.5545
  </code></pre>
  
  <p>How would I be able to fix this issue (any number trailed by 5 rounds up)? 
  Any help would be appreciated.</p>
  
  <p>Thank you.</p>
