Show HN: Pi-100 Challenge (apps.apple.com)

1 points by rrrpdx503 2y ago ↗ HN

Some people climb mountains, while others run marathons. Challenge yourself to calculate Pi by hand. For Pi Day, I created an IOS app that guides you through all the steps needed to compute Pi to 100 decimal places. Surprisingly enough, this doesn't require any complex math -- just basic addition, subtraction, multiplication and long division. Each page presents one problem to solve. Complete the problem, and move on to the next step. Take the Pi-100 Challenge, sharpen your mind, and calculate Pi.

My sugestion is to write a blog post about calculating the first 5 or 10 digits, and at the bottom add a link to your app. This may get more traction here.

Which method are you using? A long time ago I used 1+1/3+(1x2)/(3x5)+(1x2x3)/(3x5x7)+... but I wrote a program to make all the calculation.
