long double help

I am having trouble using these long doubles, I can not get them to work properly at all, I keep getting 1 for sum1 and 0 for sum2. I was just curious could give me a hint at where I am going wrong with this.

Code:

#include<stdio.h>
#include<stdlib.h>

int
main(void)
{
    long double sum1, sum2, pi;
    int i, j;

    sum1 = 0;
    sum2 = 0;

    for (i = 1; i <= 99; i+=4)
        sum1 = sum1 + (1 / i);

    printf("%Lf\n", sum1);

    for (j = 3; j <= 99; j+=4)
        sum2 = sum2 + (1 / j);

    printf("%Lf\n", sum2);


    pi = 4 * (sum1 - sum2);

    printf("pi = %Lf\n", pi);

    return 0;
}

Use floating point division:

Code:

sum1 = sum1 + (1.0L / i);
