Displaying complex version of numeric type

[LaurentPlagne]

I think that’s one of the costs of implementing a low-level type. You could look at the source for the FixedPointNumbers package to see a superset of the (relevant part of the) interface for subtypes of Real . I fear that trial and error is the only way to find the minimum needed for your purposes, and the “error” part involves this sort of detective work.

I can’t help to bring back the documentation of interface for abstract types topic. Having to dive in source code as your trial and error strategy proposal suggests is not really satisfying. I do accept that my concept/interface/traits concerns (Question about abstract type interfaces - #3 by LaurentPlagne) are related with OO way of thinking, but I also note that this question arises regularly.
