This is interesting but has no real practical use to us, just something that mathematicians like to talk about and is related to fractions, approximations, convergence and other theorems. I knew about 22/7 but this fraction is more interesting! If NASA is using 15 digits of pi for their calculations ( https://www.jpl.nasa.gov/edu/news/2016/3/16/how-many-decimals-of-%20pi-do-we-really-need/ https://www.jpl.nasa.gov/edu/news/2016/3/16/how-many-decimal... ), I’m more than happy with the 11 digits I’ve memorized :-)
