» int j, k; » double x; // Simple division of two integer: » x=7/3; » printf("x: %g\n", x); // Same but with variables: » j=7; » k=3; » x=j/k; » printf("x: %g\n", x); // More-complicated case: » x=1.14159265358979+j/k; » printf("x: %g\n", x); // The reverse just throws away the fraction: » k=x; » printf("k: %d\n", k); // See what happens when we put "3.0": » x=7/3.0; » printf("x: %g\n", x); » return 0;
