Hi, I have a problem with this very simple program:

#include <iostream>

#include <cmath>

using namespace std;

int main(){

double n=16;

double t=2.78;

double x;

x=(t/sqrt(n));

int i=0;

double u[9];

while(i<

{

u[0]=1;

i=i+1;

u[i]=u[i-1]*((1-(1/(2*i)))/(1+(x*x)));

cout <<"Iteration " <<i<<" is: "<<u[i]<<"\n";

}

system("PAUSE");

return 0;

}

OUTPUT IS:

Iteration 1 is: 0.674297

Iteration 2 is: 0.454677

Iteration 3 is: 0.306588

Iteration 4 is: 0.206731

Iteration 5 is: 0.139398

Iteration 6 is: 0.093996

Iteration 7 is: 0.0633812

Iteration 8 is: 0.0427378

Press any key to continue . .

But the output should read:

0.337148733

0.170503902

0.095808624

0.056528074

0.034305063

0.021204166

0.013276636

0.008392877

the problem is that C++ is not doing this calculation 1/(2*i)

correctly. Is there a way to force him to do this division other than

using the brackets? Thanks.
