there has been discussions on and off indicating problems with the structure of the number classes in the prelude. i have found a discussion paper by mechveliani but i have not found a concrete proposal on the haskell' list of tickets. i hope i can advance the process by making a concrete proposal for which i attach Haskell code and a pdf giving the rational can be found at ftp://ftp.geoinfo.tuwien.ac.at/frank/numbersPrelude_v1.pdf
if i have not found other contributions, i am sorry and hope to hear about them.
