title: Convert Java Number to BigDecimal : best way
body: <p>I am looking for the best way to convert a Number to a BigDecimal.</p>
  
  <p>Is this good enough?</p>
  
  <pre><code>Number number;
  BigDecimal big = new BigDecimal(number.toString());
  </code></pre>
  
  <p>Can we lose precision with the <code>toString()</code> method ?</p>
