PI Approximation Day
Today is PI approximation day. It makes more sense if you're British but today's date is the 22nd of July, or for math cognoscenti 22/71. A long time ago I had Mathematica crunch out 50,000 digits of PI for me but today I'm taking things farther: I've written Hobbitwerk::PIdigit, a tool to grab any number of digits from PI. I got 500,000 digits from Mathematica but after an hour or so of a little program I wrote called Eve inserting values into my database, I stopped at 150,000 digits. Check it out.
Happy PI Approximation Day!
122/7 is an approximation of PI - but it has been proven to be inaccurate. PI, like many other special numbers, remains in our world only as an approximation.
