-What's the meaning of this float? -Just kugel it!
[kugel] is some kind of search engine, using [list-find]: you input a search term (float or symbol in a message box) in the second inlet,
and then one or many lists where to search (separated by commas) in the first inlet.
The output is the set of lists containing the search term (first outlet). You have to connect the outlet directly to a message box.
Finally you can specify the position of your search term in the list, e.g. retrieve only lists where "x" is the first element.
This position is defined in the third inlet (zero-based).
These results are sent to the second outlet.
Hope this can be usefull,
