Decomposing numbers into arbitrary bases *already* exists as showIntAtBase. Vikas's proposal is about generalizing this existing function to output more than just strings and characters. Whether the existing naming scheme makes sense is a separate issue. (The whole Numeric module is weird, from the non-hierarchical name through function like showFFloatAlt.)

Please let me know thoughts/concerns if any to this proposal.
That is, you want to decompose a number into digits of an arbitrary base? I would not associate that with "show". I have implemented this in some flavors: https://hackage.haskell.org/package/numeric-prelude-0.4.2/ docs/Algebra-IntegralDomain.html#v:decomposeVarPositional decomposePositional in http://code.haskell.org/~thielema/htam/src/NumberTheory.hs _______________________________________________ Libraries mailing list Libraries@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/libraries
