Uhh. That article. It says: "Because computers – which are machines of precision and exactness – are often made to deal with unprecise and inexact numbers (such as pi, and irrationals) [...]"
It just bugs me. There is nothing unprecise or inexact about the number pi. Ahh, very interesting topic nonetheless.

- trsohmers 11y agoIf you look at slide 12 of the linked presentation of this thread, you can see that John says that Pi is an exact number... The VR world article tries really hard, but falls flat when it comes to actually describing unums (I've been working with John and unums for a little over a year at this point).
