title: DecimalFormat WITHOUT scientific notation
body: <p>I have a DecimalFormat like this:</p>
  
  <pre><code>DecimalFormat df = new DecimalFormat("#,###.###");
  </code></pre>
  
  <p>Then I have 3 methods which just return a float value for time, potential and current, with many decimals in case of the two last ones. So I'm trying to get an output message with the 3 values formated, so:</p>
  
  <pre><code>System.out.println("t="+df.format(getTime())+"(s), v="+df.format(getPotential())+"(V), i="+df.format(getI())+"(A)");
  </code></pre>
  
  <p>Time just count seconds from 0 to 10, without any decimal, and looks ok until it gets to 10. Then it shows 1E+1. I just don't understand why, since I have read at the API and it shouldn't be in scientific notation if I don't use an 'E' character at the DecimalFormat.</p>
  
  <p>Also, potential goes from 0 to a certain value, using 3 decimals. Looks OK, but from 0 to 0.01, it appears with 4 decimals, being the last one always 0.</p>
  
  <p>Any explanation to this behaviour of DecimalFormat? What am I doing wrong?</p>
