Hi Everyone,
We are using xalan 2.7.0 in our product. I recently faced an issue which
I found exists in Java Double.
In nodeset summation using double the output is not precise

In class org.apache.xpath.functions.FuncSum#execute, double is being
used. It all works perfectly fine but when I debugged the source I found
the problem occurs after summation is done in the line after returning
from toDouble() in
sum += s.toDouble();
when I did a test on a seperate Java sample I faced a similar result. It
appears that using BigInteger could help resolve the problem.
Thanks & Regards,
