This is just a test. The value in the 4th test seems to come from 21 iterations only. The stopping criterion is not working also. Did I get it wrong?

Oops! my bad, I calculated the stop criterion incorrectly.

This is a pretty lame solution, but it is all you asked for...

It was just a first step for demonstration. More tests to come.
