List.GroupByKey fails



Hi all,

List.GroupByKey doesn’t give the correct result. My intention is grouping a list of points based on Y.coordinate. I don’t know why it fails.



It’s a precision thing. Use a Math.Round node to round the values to the nearest 0.00001 or so.


Thx Jacob! Your reply helps me since always.


Don’t forget to mark if a post is a solution.
