RE: Summation and NaN

Hi Wendell and Katie,

I was looking through the XSLT "bible" (Mike's book :)) and noticed that by
using xsl:decimal-format that you can set a string to be the output when the
values are NaN or infinity.

In the top-level of the stylesheet you could use
<xsl:decimal-format NaN="" infinity="Out of Range" />

The pages are 187-192 of version 1 of the XSLT Programmers Reference, and an
example is given on pp192.

Cheers,

Tim Watts

Katie,

<xsl:variable name="sum"
select="sum(Borrower[Rank=1]/AssetSet/Asset/Amount)"/>
<xsl:choose>
   <xsl:when test="$sum">
     <xsl:value-of
       select="format-number($sum, '$.00')"/>
   </xsl:when>
   <xsl:otherwise>&#160;</xsl:otherwise>
</xsl:choose>

That's a clean way to do it. It'll give the space if your sum is either 0
or NaN. If you want "$0.00" when it's 0, change the test to "$sum or
($sum=0)".

Others may come up with more magical ways.

Enjoy,
Wendell
