SetDifference node

Wrong answer … 3 points
Right answer … 1 point

Help ?

Check if X, Y, Z of each points are equal in this lists.

Thanks Robert2017 for the reply
The problem is that my points derive from calculation
They are not the same because there is tolerance … the difference node does not see the same
That is, the node does not work
