I'm working on getting my C++ skills out of mothballs, and I wrote up this program to approximate the value of Pi/4 based on the series 1 - 1/3 + 1/5 ... etc.
https://github.com/asherabrams/PiSeries01 When I created the filename as a single word, it came out "piseries", and it occurred to me I had just coined a new word; it might describe a condition such as a bladder infection or a kidney stone.
Hope you have a great weekend, free of piseries and other uncomfortable ailments.
