C++ sort() Sorts array of doubles in backwards order, uses greater<>() function

#include <iostream>
#include <algorithm>                  //for sort()
#include <functional>                 //for greater<>
using namespace std;
// array of doubles
double fdata[] = { 119.2, 87.4, 33.6, 55.0, 11.5, 42.2 };
int main()/*  ww w  .j av  a2s  .c o m*/
{                                  // sort the doubles
    sort( fdata, fdata+6, greater<double>() );
    for(int j=0; j<6; j++)             // display sorted doubles
       cout << fdata[j] << ' ';
    cout << endl;
    return 0;
