Thread: Programming Rounding Numbers

I got what you meant, but still takes time to give an answer, I dont know now what is the problem but I have one solution to the problem. Thank you.

Code:

#include<iostream>
using namespace std;

#include<cmath>

double roundtohundreths (double);
int main()
{
  char t = 'Y';
  double x;
  while( t != 'N' && t != 'n' )
  {
    if ( t == 'Y' || t == 'y' )
    {
      cout << "Enter number: ";
      cin >> x;
      while( char() != '\n' );
      cout << "Original value is: " << x << endl;
      cout << "Rounded number is: " << roundtohundreths( x ) << endl;
    }
    cout << "Type Y for entering a number ( N to end ): ";        
    cin >> t;
    char t += t = 'Y' // im not sure whether to add this to
                                       // give an immediate answer
  }
  return 0;
}
double roundtohundreths (double a)
{
  double roundto = floor( a * 100 + .5 ) / 100;
  return roundto;
}
