c++ - recursive tracing output sum of series -

why recursive method not giving me answer of 2.2833?

   double m(int i)    {        if (i == 1)         return 1;       else         return (1/i) + m(i -1);    }     int main()    {         double value=m(5);         cout << value << endl;          return 0;    } 

the answer 1?

because 1/1 1 , 1/2 = 0 (1/3 = 0 ....)

so need 1.0/(double) i

then 1.0 / 2.0 = 0.5

#include <iostream>  double m(int i)    {        if (i == 1)         return 1;       else         return (1.0/(double) i) + m(i -1);    }  int main(int,char**) {     double value=m(5);     std::cout << value << "\n";     return 0; }
