testing for integers

Hi, I want to prompt the user for a data of type double.  But if it is an integer, I would do want to do something extra with it.  How do seperate integers from those that are not?  I try to make a logorithm using mods, divisions, but still end up in the mud.  Please help.

double D;
int i;

cout << "enter a number ";
cin >> D;

i = D; // truncate to an integer.  (i.e. 2.5 becomes 2.)

if (i == D) // if D was an integer, then
  // do something special.

Let me know if you have any questions.
