ORA-03206: maximum file size of (5242880) blocks in AUTOEXTEND clause is out of range

Today when I want to change max size of datafile I got strange error.

ALTER DATABASE DATAFILE '/u01/app/oracle/oradata/MYDB/users01.dbf' 
AUTOEXTEND ON NEXT 1280K MAXSIZE 32GB  
ORA-03206: maximum file size of (5242880) blocks in AUTOEXTEND clause is out of range

Here is reason: The maximum file size for an autoextendable file has exceeded the maximum number of blocks allowed.

After research internet I found that instead of using 32GB we can use 32767M. (same values but in MB).
Or you may use 31GB too.

ALTER DATABASE DATAFILE '/u01/app/oracle/oradata/MYDB/users01.dbf' 
AUTOEXTEND ON NEXT 1280K MAXSIZE 32767M;
