The above table shows for each value of m and n the results of (I) converge to a form of, where r, p and q are integers. As m and n are very large values, (I) converges to small numbers or tends to zero. This means that we obtain many square roots of ratios of rational numbers that give approximate to Pi, namely

For example, we consider the given series with m = 8 and n = 9 from the above table, give

The Pi approximation can be computed by using (II) as follows

, which is good for 3 digits.
