Problem with numerical data in Arrow.jl

[Giobbe]

Hello to everyBody.
I am trying to use Arrow.jl to store my DataFrames from a e-commerce DB and I noticed that the import function doesnt convert properly decimal values in the dataframes.

I post the comparison with CSV. Both switch my numbers to Float64 but CSV stores them properly.

I think I should need first to search for any FP columns in my original dataframes, convert them to Float64 and then store to Arrow files, but I wonder if there is a faster and simpler way like some arguments in the .write Arrow function…
Any helps will be appreciated
Giacomo
