printf not working with long type (resolved)
Code:
long stirling1(int n)
{
double nd = n;
return ( pow(nd,nd) * exp(-nd) * sqrt( (2 * PI * nd) ));
}
Code:
long stirling2(int n)
{
double nd = n;
return ( pow(nd,nd) * exp(-nd) * sqrt( (2 * PI * nd) ) * (1 + 1/(12*nd)) );
}
Code:
for(int i = 1; i<=input; i++)
printf("%4d %14d %20.10e %20.10e\n", i, factorial(i), stirling1(i), stirling2(i));
The above code does not print the correct values for stirling1() and stirling2(). I think this has something to do with the printf because when i change the "%20.10e" to "%20d" the numbers are correct in decimal form. I know the calculations are right, but i can't figure out why the printing is wrong.
Here is the output:
