#include "doublefann.h"
#include "fann_cpp.h"
#include <iostream>
using namespace std;
int main() {
FANN::neural_net* sth = new FANN::neural_net();
sth->create_standard(3, 1, 2, 1);
double inputs[1] = {0.000005};
double outputs[1] = {0.8};
double *wynik;
for(int i = 0; i < 1000; i++) {
sth->train(inputs, outputs);
wynik = sth->run(inputs);
cout << wynik[0] << endl;
}
}
I've got: 5.20981e-315, 5.201e-315, 5.19371e-315, 5.18769e-315, 5.18269e-315, 5.1786e-315.
What I am doing wrong?

Ok. I've got it. On http://leenissen.dk/fann/forum/viewtopic.php?t=354 is a solution. If you include "doublefann.h" you should link "-ldoublefann" instead "-lfann" in compiler options.
