Not much at all. Which is why I tend to stop at the 1/5602 when I use my value for Pi in unit frations.

AND I have read about how they use unit fractions. I have been doing them for quite a bit of time on here and GHMB.

There was no insult to my link just showing various degrees of accuracy for Pi and, as is often the case, different ways to get an answer with unit fractions.

I am not obsessed with things to get bent out of shape. No harm, no foul!

Have a good day!
