In the 4,000-year history of research into Pi, results have never been as prolific as present. This book describes, in easy-to-understand language, the latest and most fascinating findings of mathematicians and computer scientists in the field of Pi. Attention is focused on new methods of high-speed computation.
From the reviews: SIGACT NEWS "The book is sprinkled with many gems. The book is a treasure of information and is fun to read. The CD-ROM is in ready-to-run format (you can start using it right out of the box). Its inclusion alone is worth much more than the price of the book. I loved this book. In fact, I've pretty much run out of superlatives.I would recommend it to anyone who is just curious about pi, or about large-precision arithmetic in general, as well as to the professional who is looking to break the next N-digit barrier. Who knows, perhaps a reader will be inspired to invent a faster yet method for such algorithms."
