It's here now! The Pi-app, not apple Pie, but the numerical Pi.
Extract from the sales-pitch in the App Store:
Are you in Pi? The question is actually: is your birthday in Pi? Is your friend in Pi? Well, let's say you were born June 21 '82. Then enter 62182, or maybe 062182, or 210682 and find out if you're in Pi. You'll know in a second.
π (pronounced pi) is the ratio of a circle's circumference to its diameter. Simple, sure, but π is a mystery!
With this app you can find out if any of the numbers that occur in your life are among the first 1 million (one million) decimal places of Pi, and if so, on what decimal place. Find out if your birthday is there, or your phone number, or postal code, lottery number, salary, etc. Or search for your friends' numbers. Look, look and look up any numbers at any time.
You can also just browse through all the decimals in order to see if you can spot any patterns. Press a button and you get served a page with over 26 000 lines and 38 digits in each. You can copy a few lines and paste into an email.
