             Summary: SubString Review of Double and Integer Parameters
                 Key: VXQUERY-36
                 URL: https://issues.apache.org/jira/browse/VXQUERY-36
             Project: VXQuery
          Issue Type: Bug
            Reporter: Preston Carman


The handling of double arguments to fn:substring is not correct. Using intValue 
on the double will truncate the value, while the specification says that it 
needs to be rounded (http://www.w3.org/TR/xpath-functions/#func-substring). I 
would propose to leave it as-is for now and to fix it using our implementation 
for fn:round once that it available. If that's what we do, we should file a bug 
to ensure that we don't forget it.
