Hi - many thanks in advance for any help on the following problem:

Can anyone explain me the following behavior with basic math functions ?

I'm doing additions and substractions in an xsl sheet, and don't get the expected results.

my xml file: (dummy.xml)
-------------------------------
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="t2.xslt"?>
<ROWSET>
<ROW>dummy</ROW>
</ROWSET>
-------------------------------
the stylesheet: (t2.xslt)
-------------------------------
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:variable name="var1" select="2.4" />
<xsl:variable name="var2" select="0.2" />
<xsl:template match="/">
<html>
<ul>
<li><xsl:value-of select="$var1 + $var2" /></li>
<li><xsl:value-of select="$var1 - $var2" /></li>
</ul>
<hr />


 </html>
</xsl:template>
</xsl:stylesheet>
-------------------------------
the output: (using msxsl dummy.xml t2.xslt
-------------------------------
< h t m l >
< u l >
< l i > 2 . 6 < / l i >
< l i > 2 . 1 9 9 9 9 9 9 9 9 9 9 9 9 9 9 7 < / l i >
< / u l >
< h r >
< / h t m l >
-------------------------------

I would need the result of $var1 - $var2 to be = 2.2, as expected

The behavior is identical when using the parser in xmlspy.

Any hint ?

thanks in advance

Nicolas
