pi to 500k decimal places - Brossura

The power of pi is not immedately evident from a glance at this small Greek letter. Yet the existence of pi has confounded mathematicians and engineers for centuries. What does it mean to have a real number that cannot be stated exactly? What is a number that does not appear to have any recurring pattern? And why does it crop up in unexpected places that have no apparent connection with the circumference of a circle? These questions are not answered in this book, but you do get a glimpse of the phenomenon—real numbers to grapple with. A bit of the history of pi. And a program designed to generate as many digits as you’d like.
