SQL "cast" rounding for tsm v 5 vs v6

[sra006]

Hello ,
I am running the following script to get the nodes throughput within a time interval

SELECT cast(a.entity AS varchar(9)) AS "Node name", -
CAST(sum(a.bytes/1024/1024) AS decimal(8,2)) AS "MB Xfer ", -
CAST(sum(a.bytes/1024/1024/1024) AS decimal(8,2)) AS "GB Xfer " -
FROM summary a, nodes b WHERE a.entity=b.node_name and a.activity='BACKUP' AND -
a.start_time> current_timestamp - $1 hours GROUP BY a.entity

Somehow when I run this on tsm v6 the results are rounded up and there are zeros after the decimal point
Node name MB Xfer GB Xfer
---------- ----------- -----------
AUSORAFIN 50160.00 47.00
CHR7Z035 2365.00 2.00
CHR7Z036 1332.00 1.00

While similar report on the V5 does produce the fractions
Node name MB Xfer GB Xfer
--------- ---------- ----------
USCP3005 917.69 0.89
USCP3006 883.84 0.86
USUS3001 1411.19 1.37

Is there a way to get the fraction work in V6?

Thank you ,
Alex

SELECT cast(entity AS varchar(9)) AS "Node name", -
CAST(DEC(sum(bytes))/1024/1024 AS decimal(8,2)) AS "MB Xfer ", -
CAST(DEC(sum(bytes))/1024/1024/1024 AS decimal(8,2)) AS "GB Xfer " -
FROM summary WHERE activity='BACKUP' AND -
start_time> current_timestamp - $1 hours GROUP BY entity
