             Bug #: 15394
           Summary: Inaccurate imaginary part of catan result, real part
                    of catanh result
           Product: glibc
           Version: 2.17
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
        AssignedTo: unassigned@sourceware.org
        ReportedBy: jsm28@gcc.gnu.org
    Classification: Unclassified


catan can produce results with inaccurate imaginary part from the use of log of
numbers very close to 1; likewise, catanh can produce results with inaccurate
real part.  For example, on x86_64, catan (0x1p500i) produces imaginary part 0,
and catanh (0x1p500) produces real part 0, when the expected value is
3.0549...e-151 in each case.
