Read binary file

[jaca]

Hi,
I am with problem in the reading of a binary file.
I made thus:

#include <QApplication>
#include <QDataStream>
#include <QFile>
#include <QVector>
 
#include <iostream>
using namespace std;
 
int main(int argc, char *argv[]) {
 
   QApplication app(argc, argv);
 
   QFile file("wavemin_501ns.ad");
   file.open(QIODevice::ReadOnly);
   QDataStream in(&file);    
 
   qint64 tam = file.size();
   qint64 ns = tam/sizeof(float);
   QVector<float> vet(tam);
   in >> vet;
 
   for (int i = 0; i < 50; i++)
      cout << vet[i] << " " << i << endl;
   cout << ns << endl;
 
   return 0;
}

#include <QApplication>
#include <QDataStream>
#include <QFile>
#include <QVector>

#include <iostream>
using namespace std;

int main(int argc, char *argv[]) {

   QApplication app(argc, argv);

   QFile file("wavemin_501ns.ad");
   file.open(QIODevice::ReadOnly);
   QDataStream in(&file);    

   qint64 tam = file.size();
   qint64 ns = tam/sizeof(float);
   QVector<float> vet(tam);
   in >> vet;
   
   for (int i = 0; i < 50; i++)
      cout << vet[i] << " " << i << endl;
   cout << ns << endl;
  
   return 0;
}

To copy to clipboard, switch view to plain text mode 

But the values returned for vet[] are not equal to the values of binary file.
Somebody can help me, please?
Thank you.
