   #include <stdio.h>

   int main(void) {
      float media1,media2,media3,matematica,romana,istorie;
      printf("Notele primului elev snt/\n");
      scanf(" %f %f %f",&matematica,&romana,&istorie);
      media1 = (matematica+romana+istorie)/3;
      printf("media primului element %f",media1);
      printf("\n");
      if(media1>=9)
        printf("fasfsafsaf");
      else if (media1>=8){
        printf("fgegegeg");
      }
     else if((media1<   5.6) || (media1<=6.3f)){
        printf("equal");
     }  
return 0;
}

Why this does not print 6.3 ? If i provide something like float x = 6.3; and test media1 <= 6.3 it will print equal.

The input is 6.3 6.3 6.3 – maimu_21 Oct 01 '15 at 21:01

well if you are solving your problem with floats, you now have 2.00000001 problems... – Łukasz Oct 01 '15 at 21:05
Try `printf("media primului element %.12f %.12f",matematica, media1);` --> `6.300000190735 6.300000190735`. – chux - Reinstate Monica Oct 01 '15 at 21:07
Thanks ,that was the answer I was thinking but the think that tricked me is that i added float x = 6.3; and then i added the condition media1 <= 6.3 but that was true since 6.3 is the same as x . – maimu_21 Oct 01 '15 at 21:08
If you use `double`, then `printf("media primului element %.20f %.20f",matematica, media1);` --> `6.29999999999999982236 6.29999999999999982236` – chux - Reinstate Monica Oct 01 '15 at 21:10
else if((media1< 5.6) || (media1<= (float) 6.3 )){ printf("equal"); } And why this prints equals ? – maimu_21 Oct 01 '15 at 21:16
