boost::normal_distribution funktioniert nicht

[numbercruncher]

#include <iostream>
#include <boost/random.hpp>
using namespace std;
using namespace boost;

int main()
{
    mt19937 generator(42);
 	normal_distribution<double> boostNormalRand(100,5);

    cout << "Mittelwert:"          << boostNormalRand.mean()  << endl;
    cout << "Standardabweichung: " << boostNormalRand.sigma() << endl;    

    for(int i=0; i<30; ++i)
        cout << boostNormalRand( generator ) << " ";   
}

Ergibt keine richtigen Werte (nur -1.#IND). Kann da jemand Unterstützung bieten?

Damit sollte es funktionieren.

#include <boost/random.hpp>
#include <conio.h>
#include <iostream>
using namespace std;

int main()
{
 boost::mt19937 generator;
 boost::normal_distribution<> normal_dist(90,5);
 boost::variate_generator< boost::mt19937&, boost::normal_distribution<> > random(generator, normal_dist);

 cout << "Mittelwert:         " << normal_dist.mean()  << endl;
 cout << "Standardabweichung: " << normal_dist.sigma() << endl; 
 cout << "Varianz:            " << normal_dist.sigma()*normal_dist.sigma() << endl << endl; 
 for (int i=0;i<30;++i)
     cout << random() << endl;

   getch();
}
