Accepting Decimals

Is there a library or header file that gives a command that accepts decimals? I have been trying to get decimal input from the user but when I output it, it only prints the numbers before the decimal. Either a header file or I am doing something wrong.

Here is what I am trying to make (example):

Code:

---

#include <iostream.h>
#include <stdlib.h>

int main()
{
  long a;
  system("CLS");
  cout<<"Please enter a decimal number: ");
  cin>>a;
  cout<<"\nThe number you entered is "<<a<<endl;
  system("PAUSE");
  return 0;
}

// Here is what I got:
/*
Please enter a decimal number: 1.23

The number you entered is 1
Press any key to continue...
*/

You have to use float or double for decimals. Int and long can't handle them.

Don't use header files with .h extensions. For the equivalent header files and an explanation of the using directive you also need with the new header files see here:

Get rid of:
system("CLS");

Change this:
system("PAUSE");

to:
cin.get(); //waits for the user to hit any key

Any key that has enter written on it :)
I find it's a lot easyer to just run console apps from, well, the console.
