I would like divide one column by another one. But one of the columns is string and not number. If I would loke to use the node “String to Number” I receive the error message “Values in 3 cells could not be parsed, first error: ‘-1,490,000’ (RowKey: Row9150_?Row34???_?, Position: 23)”.
I assume that KNIME has a problem with the negative value. Do you have any idea how to solve it?
