public class Brain {

static int range;

double calculate() {
    double sum = 0;
    for (int n = 1; n <= Brain.range; n++) {

        sum = sum + (double) (1 / n);

    }

    return sum;

}

}

I am always getting the return as 1.0. I tried to understand it here, but no help : Harmonic sequence recursion

Integer division. Do the cast BEFORE the division, not after. – Dawood ibn Kareem Jan 23 '17 at 07:12

i didn't see any recursion here – Baby Jan 23 '17 at 07:13
that is, do `sum = sum + ((double) 1 / n);` or just `sum = sum + (1.0 / n);` – user85421 Jan 23 '17 at 09:24
