             Bug #: 13840
           Summary: hypotf overflow and underflow
           Product: glibc
           Version: 2.15
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
        AssignedTo: jsm28@gcc.gnu.org
        ReportedBy: jsm28@gcc.gnu.org
    Classification: Unclassified


sysdeps/ieee754/flt-32/e_hypotf.c's implementation of hypotf overflows
internally for some large inputs (for example, giving inf for hypotf (0x3p125,
0x4p125) instead of 0x5p125).  It also gives inaccurate results for some small
inputs that are not subnormal.  I'll send a patch.
