format-number

Hi I'm having a problem with format number.

This is my xml file:
<?xml version="1.0" encoding="ISO-8859-1"?>
<test>12.00</test>

This is my xsl code:
<?xml version='1.0' encoding='UTF-8' ?>
<xsl:stylesheet version='1.0'
xmlns:xsl='http://www.w3.org/1999/XSL/Transform'>
    <xsl:template match="test">
    	<output>
    		<xsl:value-of select="format-number(., '0.00')"/>
    	</output>
    </xsl:template>
</xsl:stylesheet>

This is the output I am getting:
<output>12</output>

Shouldn't the output be:
<output>12.00</output>

I'm using xalan.

Thanks in advance.
