Hi,

In my books.xml file, each book has a price node that contains other 
nodes.  It looks like this:

<books>
  <book>
   <title>Some Title</title>
   <author>One Author</author>
   <author>Another Author</author>
   <listprice>
    <amount>1726</amount>
    <formattedprice>$17.26</formattedprice>
   </listprice>
   <ourprice>
    <amount>1531</amount>
    <formattedprice>$15.31</formattedprice>
   </ourprice>
  </book>
  <!-- other book nodes go here -->
</books>

This is what I've done:

<xsl:value-of select="substring(books/book/listprice/formattedprice, 2) 
- substring(books/book/ourprice/formattedprice, 2)"/>

Now, this works fine, but it creates a new problem for me.  For some 
books I get savings that aren't rounded.  For example, using xsl, the 
html output looks like this (I know its boring - shame on me  :-( ):

Title = 1776
ListPrice = 32.00
OurPrice = 21.12
Savings = 10.8799999999999999

Savings simply takes the result of (ListPrice minus OurPrice) and 
divides it by the ListPrice.

Is there any way to round the savings data to the nearest hundredth 
using xsl or xpath?

Thanks,
Roshawn
