Need help with DataFrame. I am reading a csv file using DataFrame.readCSV(file) but it’s messing up large number and converting them into scientific notation… how can I avoid this?

Do you have an example of some of these numbers? :slightly_smiling_face: I'm curious to see what happens with them

Oh and please also provide your `Locale.getDefault()` value, as that can influence how numbers are parsed

Looks like it's parsed as a `Double` instead of an `Int`/`Long`. The number is not converted or stored differently, but Kotlin renders `Double.toString()` like that when they become too large.

I tried to reproduce it with those numbers on my machine, but for me they are correctly recognized, so I'm not sure why they aren't on yours.
However, there's actually a way to force the types of `readCSV()` by supplying `colTypes = map("YOUR_COL_NAME" to ColType.Long)`.
