bug report: compoundnf

[Paul Zimmermann]

       Hi,

$ cat test_compoundn_glibc.c
#include <stdio.h>
#include <math.h>
 
extern float compoundnf (float, unsigned long long);
 
int main()
{
  float x = 0x1.d0004cp-32f;
  unsigned long long y = 5263617841566842879ull;
  float z = compoundnf (x, y);
  printf ("x=%a y=%llu z=%a\n", x, y, z);
}

# with glibc 2.42
$ gcc test_compoundn_glibc.c -lm
$ $BUILD/testrun.sh ./a.out 
x=0x1.d0004cp-32 y=5263617841566842879 z=-nan

The expected result is +Inf.

Paul
