  +    Velocity has a built-in way of dealing with division by zero. In the following 
example
  +  </p>
  +
  +  <p>
  +    <source><![CDATA[
  +    #set( $foo = 5 )
  +    #set( $bar = $foo - 5 )
  +    #set( $uhoh = $foo / $bar )
  +    $uhoh
  +    ]]></source>
  +  </p>  
  +
  +  <p>
  +    The reference <variable>$uhoh</variable> is assigned the value of five divided 
by zero.
  +    When Velocity renders this template, the output will be:
  +  </p>
  +
  +  <p>
  +    <source><![CDATA[
  +    $uhoh
  +    ]]></source>
