I’m doing a program that aproximate PI and i’m trying to use long long, but it isn’t working. Here is the code
#include<stdio.h> #include<math.h> typedef long long num; main(){ num pi; pi=0; num e, n; scanf("%d", &n); for(e=0; 1;e++){ pi += ((pow((-1.0),e))/(2.0*e+1.0)); if(e%n==0) printf("%15lld -> %1.16lld\n",e, 4*pi); //printf("%lld\n",4*pi); } }
