% operator problem

[henkka]

im reading this one c++ book and one of those examples had % operator so i decided to do simple program to see how it works... when i change the % operator to any other operator then it works fine but like this it doesnt

#include <iostream>

int main()
{

double x;
std::cin >> x;
double y;
std::cin >> y;

double z;
z = x % y;

std::cout << z << std::endl;

return 0;

}

Change your doubles to integers and it'll work just dandy.

The % operator is used only with integers and yields the remainder when one integer is divided by another.

6%3 yields 0
7%3 yields 1
8%3 yields 2
9%3 yields 0

The ordinary division operator when applied to integers yields the truncated integer result of the division.

6/3 yields 2
7/3 yields 2
8/3 yields 2
9/3 yields 3
