Note that Pi (the ratio of the circumference of a circle to its diameter) can be approximated very accurately by just dividing 355 by 113. For most applications, that works very well. One has to wonder why we learned 22/7 in grammar school, when 355/113 was always available and far more accurate. Any ideas why 22/7 is still being taught?

On the other hand, I've been using Doogle's VB6 solution for years.
