This is not a game. I only get a little bit of time to use WiFi on my computer, so I thought about putting something I made when I was bored... on my board... on here with my phone!
This is me calculating a very good approximation of the square root of 2 by hand. My original approximation - what I remembered - was 1.4142. I improved this value using math to 1.414213562431 (10 digits correct), and was surprised by how much the error went down!
