             Bug #: 13726
           Summary: the result of  wprintf (L"%La\n", (long double)
                    22.625); is 0xb.bp+1, but the correct result should be
                    0xb.5p+1
           Product: glibc
           Version: 2.14
            Status: NEW
          Severity: normal
          Priority: P2
         Component: stdio
        AssignedTo: unassigned@sourceware.org
        ReportedBy: no.1zhouzhonghua@163.com
    Classification: Unclassified


in the file sysdeps/x86_64/fpu/printf_fphex.c there is one expression in line
60:
leading = *numstr++;
but i think is should be like this :
 leading = *numstr++;                            \
 ++wnumstr;                                     \

I'm confirming the bug

Small test program:

#include <stdio.h>
#include <wchar.h>

int 
main (void) {

  long double x = 22.625;

  //printf ("%La\n", x);
  wprintf (L"%La\n", x);

  return 0;
}

It gives indeed different outputs for printf and wprintf.
