How to use ceil() function to rounds N upward and get the smallest value that is not less than N in C++

Answer 1

#include <iostream>
#include <cmath>

using namespace std;

int main()
{
	cout << "ceil(4.3) = " << ceil(4.3) << endl;
	cout << "ceil(6.8) = " << ceil(6.8) << endl;
	cout << "ceil(-4.3) = " << ceil(-4.3) << endl;
	cout << "ceil(-6.8) = " << ceil(-6.8) << endl;
	cout << "ceil(-0.0) = " << ceil(-0.0) << endl;

	return 0;
}


/*
run:

ceil(4.3) = 5
ceil(6.8) = 7
ceil(-4.3) = -4
ceil(-6.8) = -6
ceil(-0.0) = -0
