// Purpose - a rounding algorithm that uses type casting

#include <cmath>
using namespace std;

int main()
{
	double num = 0.0;
	double roundedNum = 0.0;

	cout << "Enter a number with more than 2 decimal places: ";
	cin >> num;

	roundedNum = (static_cast <int> ((num * 100) + 0.5))/ 100.0;

	// or 
	// roundedNum = (int ((num * 100) + 0.5))/ 100.0;	using old-fashioned type casting
	// or
	// roundedNum = (floor ((num * 100) + 0.5))/ 100.0;	using the floor library function
	//							from cmath or math.h which must be
	//							included at the top of the program

	cout << num << " rounded to the nearest hundredth's is " << roundedNum << endl;	

	return 0;
