Today is 3/14 (In America, sorry everyone [?] else). This is Pi day.
I present a "fun" program that kinda calculates an approximation for Pi. It uses a Monte Carlo method, which isn't exact, but can get close over time. Being in PICO-8, it can't run for very long before running out of memory, but it still kinda works.
For more on Monte Carlo methods, I adapted mine from this Wikipedia page
fun fact: If you edit the program to have the line srand(314) toward the top, it will get 3.1416, the closest you can get to Pi with only 4 decimal places (It would be 3.1415, but the next digit is 9, so rounded, it's closer).

Nice. We did this same thing as an exercise at the beginning of my computational physics course in my undergrad.
