Bug or is it me?

Hello List:

    Is this a bug?Or is it me?

    [code]

    /* Created by Anjuta version 1.2.4 */
    /*    This file will not be overwritten */

   #include <iostream>
   #include <fstream>

   using namespace std;

   int main()
   {
   
   
   
    double x = 0;
   
   
    x = -2.3;
    while(x <= 2.1)
    {
        cout << x << endl;
        x += 0.1;
    }
   
    return (0);
   }
 
    [code]


    When I run this little program I get the following output:


    -2.3
-2.2
-2.1
-2
-1.9
-1.8
-1.7
-1.6
