>Description:
Using fstream or iostream for output to file or standardo out, the directive
"hex" should display the output as a hex number, but actually displays as
some floating point junk.	This code works as expected with the 3.0.2
compiler.
>How-To-Repeat:
#include <iostream>
#include <fstream>
using namespace std;
main()
{
    long    i = 100;
    ofstream des;
    des.open("/tmp/des.out.txt");
    des << hex << i << endl;
    des << dec << i << endl;
    cout << hex << i << endl;
    cout << dec << i << endl;
}

Expect this code to print out "64" and then "100".  But actually outputs
"2.14315e-312" and "100".
I have collected information available.
