Re: Numeric supports base 8, 10, 16 but not 2 -- why?

I need binary encode/decode about once every six months, and I too find it annoying that these are missing. +1 from me. On Sun, Dec 6, 2020 at 3:09 PM Tikhon Jelvis wrote:

Absolutely agree on this. I've needed to render a number in binary a couple of times, and each time I had to stop and think about how to use showIntAtBase. It's not hard per se, but it is really fiddly. The expression I end up using is hard to understand at a glance and uses a scary-looking (but safe-ish) partial function:

showIntAtBase 2 ("01" !!) x ""

A dedicated function is a clear improvement, although the ShowS bit is still unnecessarily fiddly for use outside implementing Show instances:

showBinary x ""

To be honest, I really don't like the Numeric module at all. I use hex a bit more often than binary, but I just do it with printf. I was going to suggest adding %b to printf alongside this change, but it looks like Text.Printf already supports it! So while I think adding showBinary absolutely makes sense, I'll probably just use printf myself going forwards.

Base 2 +1 +1 +1 = Base 5 - Is this, what we want? _______________________________________________ Libraries mailing list Libraries@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/libraries
