I have i file which contains a column with 19 digits identification number (only numbers). KNIME File reader node identifies it as Double. And that would be OK, but the number is not the same as in my source. For example (real cases):
But in KNIME then i get:
As you see the last 2-3 digits are complete miss. But if i manually change the ID format to String, i get everything correctly.
So, if KNIME is not able to deaql with Long numbers, why, while importing, it can not automaticallly choose format String if it founds Long numbers. And then, what is the maximum Double the KNIME can deal with?
