Pi never ends. Someone has calculated it to 51.5 billion digits, but it goes on way beyond that. Go to the web page link to see the first 10,000 or so digits. In its most basic usage, if you take the diameter of a cirle, and multiply it by pi, you get that circle's circumphrence. As a side note, is there any pratical usage for knowing pi to a whole bunch of digits? or even the 10 the calcs give us? We very rarely use any other number with that many significant digits in an equation with pi. So wouldn't proper scientific notation cancel out all those digits. (I'm not trying to put down pi, I know calculating pi is a good way to test computers, plus it's fun :) Then again, I heard some woman was testing a weather modle somewhere, and accidently changed the number of digits it woked with down one, and the model predicted a completly diffrent forcast for the next week. I can beleive that. I'm babbling, so I'll stop now :P

are you sure about that? It looks to me like 22/7 is closer. pi is approx. 3.1415926525898 and 22/7 is approx. 3.1428571428571 and 3.14 is 3.14. Thus the difference between pi and 22/7 is 3.14285714285713.1415926525898, or 0.0012644892673. The difference between 3.14 and pi is 3.14159265258983.14, or 0.0015926535898. Taking the difference between those, 0.00159265358980.0012644892673 gives us 0.0003281643225, meaning that 22/7 is closer by 0.0003281643225, or 0.010445794814456 percent of pi. That might not be the true way to do it, so i am going to find out the percent of themselves that they are off of pi...*switches back to vti*
...
0.0012644892673 is 0.040233749414091 percent of 22/7.
0.0015926535898 is 0.050721451904459 percent of 3.14.
So you might be able to say that 22/7 is 0.0104877024903680 percent closer to pi than 3.14. Either way, it seems that 22/7 is closer than 3.14.
Did i make a mistake? BTW, can't wait for March 14, 2016 at 9:26 and 52 seconds! (3/14/16 9:26:52)
