Except that with xpheas method, you lose all the benefits of arbitrary precision as the * operator only works on int and float and those are restricted in length (See int ant float types for more information).

if you have compiled php width "--disable-bcmath", you can use this:

<?php
 
function bcmul($_ro, $_lo, $_scale=0)
  {
    return
round($_ro*$_lo, $_scale);
  }
?>
