Show all autoextendable tablespaces

In Oracle how to find all the autoextendable tablespaces:

set pages 10000

col tablespace_name format a20

col file_name format a45

col file_mb format 999999

col data_mb format 999999

col free_mb format 999999

col max_mb format 999999

select files.tablespace_name, files.file_name, ceil(files.mb) file_mb, ceil(files.mb - nvl(free.freemb,0)) data_mb,

nvl(free.freemb,0) free_mb, files.maxmb max_mb, autoextensible

from dba_data_files) files,

(select file_id, sum(bytes)/1024/1024 freemb

group by file_id) free

where files.file_id = free.file_id (+)

and files.autoextensible='YES'
