Wrong o/p giving

Question

Hi Below query is giving different o/p in different versions (I'm trying on both 10g and 11g)
On 10g it gives me correct o/p i.e correct tablespace utilisation is giving and 11g is not giving correct o/p. i.e wrong tablespace utilisation is giving
What I have analyzed is 'decode' in the statement is doing the trick.
Can some help me please?
select 'Used space for '|| a.tablespace_name|| ' in ORACL is',
round(100*(SUM(a.bytes)/1024/1024 - round(c."Free"/1024/1024))/(SUM(decode(b.maxextend, null, A.BYTES/1024/1024, b.maxextend*8192/1024/1024))))  "UPercent" ,'%'
from dba_data_files a, sys.filext$ b, (SELECT d.tablespace_name , sum(nvl(c.bytes,0)) "Free"
FROM dba_tablespaces d,DBA_FREE_SPACE c where d.tablespace_name = c.tablespace_name(+)
group by d.tablespace_name) c where a.file_id = b.file#(+) and a.tablespace_name = c.tablespace_name
having round(100*(SUM(a.bytes)/1024/1024 - round(c."Free"/1024/1024))/(SUM(decode(b.maxextend, null, A.BYTES/1024/1024, b.maxextend*8192/1024/1024))))>=70
GROUP by a.tablespace_name, c."Free"/1024
order by round(100*(SUM(a.bytes)/1024/1024 - round(c."Free"/1024/1024))/(SUM(decode(b.maxextend, null, A.BYTES/1024/1024, b.maxextend*8192/1024/1024)))) desc

For you own sanity, you really should format your code. For the sanity of those from whom you seek assitance, you should preserve that formatting with use of the \ tags;SELECT 'Used space for ' || a.tablespace_name || ' in ORACL is',
ROUND (
100
* (SUM (a.bytes) / 1024 / 1024 - ROUND (c."Free" / 1024 / 1024))
/ (SUM (
DECODE (b.maxextend,
NULL, a.bytes / 1024 / 1024,
b.maxextend * 8192 / 1024 / 1024))))
"UPercent",
FROM dba_data_files a,
sys.filext$ b,
( SELECT d.tablespace_name, SUM (NVL (c.bytes, 0)) "Free"
FROM dba_tablespaces d, dba_free_space c
WHERE d.tablespace_name = c.tablespace_name(+)
GROUP BY d.tablespace_name) c
WHERE a.file_id = b.file#(+) AND a.tablespace_name = c.tablespace_name
