The reusability of Num varies inversely with how many assumptions you make about it.
A default implementation of pi would only increase usability, not decrease it.
Suppose I believe you. (Actually, I am afraid, I have doubts.) Can you provide some examples of this "increased usability"? If possible, with a *relevant* context, which shows that PI should belong by default to the class Floating (whatever we mean by that...) Somehow I do not only think that the default implementation would be good for nothing, but that putting PI into Floating as a class member, serves nobody. I would be happy to learn that I am mistaken, but if it is just to save 5 seconds of a person who wants to pass smoothly between floating numbers of single and double precision... Jerzy Karczmarczuk
