            Bug ID: 28679
           Summary: math:log contradiction about result when argument is
                    zero
           Product: XPath / XQuery / XSLT
           Version: Working drafts
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Functions and Operators 3.1
          Assignee: mike@saxonica.com
          Reporter: pwalmsley@datypic.com
        QA Contact: public-qt-comments@w3.org

The text describing math:log says "The effect is that if the argument is less
than or equal to zero, the result is NaN."  But, the 2nd example says that if
the argument is zero, the result is -INF rather than NaN.
