Peter Elsea’s Lclose is limited to lists up to 256 items while I’d like to go up to 1000 items.

You can replace it by using zl in various flavours. Add in a patcherargs and you could make it more useful.

I’ve put patcherargs in so it works as an object, trimmed down a few objects that weren’t strictly needed and added an additional outlet that gives you the index of the closest float. You can change the maximum size by sending ‘maxsize 512′ etc.

I also restored my memory of the abs object…

Nice tricks.

I simplified a bit further Timo’s version.

Here is an abstraction-ready version.

In the interests of experimentation, I tested the two different methods here (using pedant), and my method was a tiny bit faster on average (0.00152). Not in any way significant, unless you were performing the operation thousands of times a second, but it is interesting to know.

By the way I repost because there was a bug in the former one.

Do we have any other challengers?
