says "100e" shouldn't match "%f". But I got

[hjl@gnu-6 tmp]$ cat s.c
#include <stdio.h>

int main()
{
  int count;
  float quant;
  char buf[100];
  count =3D fscanf(stdin, "%f%s", &quant, buf);
  printf ("quant =3D %lf\n",quant );
  printf ("count =3D %d\n", count);
  printf ("string =3D %s\n", buf);
  return 0;
}
[hjl@gnu-6 tmp]$ gcc s.c
[hjl@gnu-6 tmp]$ cat x.input=20
100ergs of energy
[hjl@gnu-6 tmp]$ ./a.out  < x.input=20
quant =3D 100.000000
count =3D 2
string =3D rgs
[hjl@gnu-6 tmp]$=20

I was told that Windows and MacOS behave the same as glibc.
