Problem with function returning correct value

[NOD32]

Confused here, what is wrong with my syntax?

  #include <iostream>
#include <cmath>

using namespace std;

double fallingDistance(double time)
{
	
	double distance;
	const double gravity = 9.8;
	distance = 1/2 * gravity * time * time;
	return distance;
}

int main()
{
	double trueDistance;
	double time;
	cout << "Welcome to the distance calculation program!" << endl;
	cout << "Please enter a falling time for object in seconds" << endl;
	cin >> time;
	cout << "The distance the object fell is" << endl;
	trueDistance = fallingDistance(time);
	cout << trueDistance;
	return 0;
}

  #include <iostream>
#include <cmath>

using namespace std;

double fallingDistance(double time)
{
	
	double distance;
	const double gravity = 9.8;
	distance = (gravity * time * time)/2; //updated your syntax here, easier to read and runs fine.
	return distance;
}

int main()
{
	double trueDistance;
	double time;
	cout << "Welcome to the distance calculation program!" << endl;
	cout << "Please enter a falling time for object in seconds" << endl;
	cin >> time;

	trueDistance = fallingDistance(time);
	cout << trueDistance;
	return 0;
}
