rezaeir opened a new issue #7385:
URL: https://github.com/apache/arrow/issues/7385


   I'm new with using the arrow pacakge. my code is as follows:  
   ```
   # Python
   import pandas as pd
   df = pd.DataFrame(dict(a=[1,2], b=[3,4]))
   
   df.to_feather('test.feather')
   ```
   then 
   ```
   # R
   library('arrow')
   df = read_feather('test.feather')
   data.matrix(df)
   ```
   which instead of coercing to double gives me this unusual output
   ```
   a            b
   4.940656e-324        1.482197e-323
   9.881313e-324        1.976263e-323
   
   ```
   Which part of my code is wrong or What should I do here to fix this?
