i like it; it seems i have understood
i try something like this:
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char** argv)
{double x, y;
/**********************/
if (argc!=3) { fprintf(stderr,"usage error\n");
return -1;}
x=strtod(argv[1], 0);
y=strtod(argv[2], 0);
return (x!=0.0) ? (printf("%.2f\n", y/x), 0):
(printf("Error: x==0\n"), -1);
}

yes what you say is ok for me.
