#include <iostream>
#include <cmath>

using namespace std;

int main()
{
	cout << "erfc(-1) = " << erfc(-1) << endl;
	cout << "erfc(1) = " << erfc(1) << endl;
	cout << "erfc(0) = " << erfc(0) << endl;
	cout << "erfc(-0) = " << erfc(-0) << endl;

	return 0;
}

/*

erfc(-1) = 1.8427
erfc(1) = 0.157299
erfc(0) = 1
