I have been trying to do some math calculations and comparisons with two columns. For example, I want to append new columns for the result of the comparison of the two columns' values. This process needs to compare each value in column 1 to each in column 2 (like" >= ") and then dynamically create a new column for the result with 0s and 1s.
I think it is not possible to change expression in the math node dynamically. Is there any suggestion to accomplish such a simple task?
Well, the easiest way to accomplish this would probably be to split your table so both columns are separated. Then you could rejoin them with, say, a Cross Joiner. Now you have one row for every pair and the math node is useful again. Be aware though that the cross join will produce a huge table. If that creates problems, you might want to try something else. But splittig will probably be involved in any case.
