That doesn't surprise me a lot. Apparently, you'd only need 40 digits of pi to compute the area of a circle the size of the visible universe[0]. Pi tends to show up in equations where it's being multiplied by relatively small constants like 1/2, 2, or 8. Maybe sometimes you might see a pi^2 times a smallish constant, too. So, not needing a ton of digits in order to be good enough for numerical models doesn't seem crazy at all. --- [0]: https://www.jpl.nasa.gov/edu/news/2016/3/16/how-many-decimals-of-pi-do-we-really-need/ https://www.jpl.nasa.gov/edu/news/2016/3/16/how-many-decimal...
