            Bug ID: 59987
           Summary: [C++11]: Missing ios_base::hexfloat format specifier
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: npl at chello dot at

The specifier for hexadecimal floats is missing:
http://www.cplusplus.com/reference/ios/hexfloat/
I suppose the parsing of this format isnt working either (only tested this with
gcc 4.7, but there doesnt seem to be any changes).

stringstream instream("0x1.0624dd2f1a9fcp-10");
double val;
instream >> val; // should be  0.001
