After loading data from excel as int, I used group by to sum column. The node skipped some lines offering to convert them to long. Question how? Why this function is not available in Math Note?
This is a good question, I think this is a missing feature worth adding to the node.
I added an example workflow that shows how you can cast an int column to a long column using the Column Expressions node: Cast int to long.knwf (9.7 KB)
