x05scanf("%f%f",&a,&b);

x05printf("%.2f=%.2f+%.2fn",a + b,a,b);

x05printf("%.2f=%.2f-%.2fn",a - b,a,b);

x05printf("%.2f=%.2f*%.2fn",a * b,a,b);

x05if (b == 0)

x05{

x05}

x05else

x05{

x05x05printf("%.2f=%.2f/%.2fn",a / b,a,b);

x05}

x05if ((int)b == 0)

x05{

x05x05printf("除数为0n");

x05}

x05else

x05{

x05x05printf("%d=%d%%%dn",(int)a % (int)b,(int)a,(int)b);

x05}
