Thread: pow() doesnt return a double?

Code:

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

int main()
{
      
      double result, x = 3.0, y = 2.0;
      result = pow(x, y);

      cout << result << endl;

      system("PAUSE");
      return 0;
}

The above gives me a result of 9 instead of 9.0
as the book here says.

Same thing w/ abs() or fabs() or floor() etc. The arguments are doubles but the value returned are integers.

I did something wrong or do I need to use the "cout.setf....cout.precision" thingy, but this book doesnt say anything abt it.

Thanx.
