It is essentially the same thing. It must be able to calculate pi to at least 5 decimal places. Views View Edit History. Between 3,000 and 4,000 years ago, people used trial-and-error approximations of pi, without doing any math or considering potential errors.

Now pick up a pen, close your eyes and put dots on the square at random. Because he proved pi's transcendence, Lindemann also proved, once and for all, that there was no way one could "square the circle. WriteLine s. It has been widely accepted that for most numerical calculations involving pi, a dozen digits provides sufficient precision.

DownloadString "http: Substring s. This record held for another 800 years. At this point, Archimedes's calculation is around 3. The search for the accurate value of pi led not only to more accuracy, but also to the development of new concepts and techniques, such as limits and iterative algorithms, which then became fundamental to new areas of mathematics.

See the How to Ask page for help clarifying this question. P Output: Those less than or equal to distance 1 from 0,0 are considered inside, else outside.

A Brief History of Pi

This article was originally published on The Conversation. Lowest voted answer: My understanding is that it adds up the pixels in the circle and divides by the radius, and then once again. Whether this loads a constant from ROM or actually calculates the answer depends on the processor though but on at least some, it actually does a calculation, not just loading the number from ROM.
