// Problem 3.13
// An application of function floor is rounding a value to the nearset integer.
// The statement
//         y=floor(x+.5);
// will round the number x to the nearset integer and assign the result to y.
// Write a program that reads several numbers and uses the preceding statement
// to round each of these numbers to the nearest integer. For each number
// processed, print both the orignal number and the rounded number.
//

#include <iostream.h>
#include <iomanip.h>
#include <math.h>

// GRADER: There are many ways to demonstrate this problem. Be flexible!
