That's the way things are in C (man 3 printf).

waverley:~/cfiles/misc$ cat fg.c
#include <stdio.h>

int main (void)
{
    int i;

    for (i=0; i<3; i++) {
        printf("5f:   %5f\n", (double) i);
        printf("5g:   %5g\n", (double) i);
        printf("5.0f: %5.0f\n", (double) i);
    }

    return 0;
}
waverley:~/cfiles/misc$ gcc -Wall fg.c
waverley:~/cfiles/misc$ ./a.out 
5f:   0.000000
5g:       0
5.0f:     0
5f:   1.000000
5g:       1
5.0f:     1
5f:   2.000000
5g:       2
5.0f:     2
