Couldn't resist trying this on a modern PC...

Code:


#include <math.h>
#include <stdio.h>

void main()
{
  double i,sum;
  i=1;
  sum=0;
  for(i=1;i<=10000;i++)
  {
  sum+=pow(exp(sin(atan(i))),1/3.);
  }
  printf("%lf\n",sum);
}

$ gcc sum.c -o sum -lm
$ time ./sum 
13955.857904

real    0m0.005s
user    0m0.005s
sys    0m0.001s
$

In Windows 11 on a Core i9 I get this:
