How to round number values

Hi,

I have to round a number value and don't know how to do this. 
My XML file looks like this: 

<lzus>PS: 110, Kw: 81, ccm: 1896</lzus>
<lipr>48064.63999</lipr>


the XSL - part is

...
      <xsl:value-of select="lipr"/>
...

with this I get "48064.63999" but I need "48.064,64".

How could I format the number ?

Thanx in advance

Moritz.
