title: PHP - number_format issues
body: <p><code>number_format</code> <strong>stupidly</strong> rounds numbers by default.  Is there just a simple way to turn off the rounding?  I'm working with randomly generated numbers, and I could get things like...</p>
  
  <p>42533 * .003 = 127.599 or,<br>
  42533 * .03 = 1275.99 or,<br>
  42533 * .3 = 12759.9</p>
  
  <p>I need number_format (or something else) to express the result in traditional U.S. format (with a comma separating the thousands) and <strong>not</strong> round the decimal.</p>
  
  <p>Any ideas?</p>
