[xsl] round-half-to-even problem.

Hi, 

I'm using saxon 9 EE and xslt 2.0.
I want to round but I'm getting weird outputs.

My Template looks like this:

<xsl:template match="data">
                <absatz>
                        <xsl:choose>
                                <xsl:when test="@type='Number' and
string-length(substring-after(., '.')) &gt; 2">
                                        <xsl:value-of
select="round-half-to-even(text(), 2)"/>
                                </xsl:when>
                                <xsl:otherwise>
                                        <xsl:apply-templates/>
                                </xsl:otherwise>
                        </xsl:choose>
                </absatz>
</xsl:template> 


Example:
<data type="Number">1351.845</data>

Output:
<absatz>1351.84</absatz>

Desired:
<absatz>1351.85</absatz>

Example:
<data type="Number">298.15499999999997</data>

Output:
<absatz>298.16</absatz> <- which is correct or at least what I want.

Can anybody explain this to why on time it takes the bigger and the next
time the smaller number ?!
Can I control that somehow ?!

kind regards
