Hi TSM/SP-ers!
I have something weird when using te following SQL queries:

select sum(fs_used_size),sum(fs_total_size) from sysibmadm.snapstorage_paths

           Unnamed[1]                Unnamed[2]
---------------------     ---------------------
          74434565120              692060160000

Now, when I try to calculate a percentage, I get the following result:

tsm: AMSE3>select cast(sum(fs_used_size)*100/sum(fs_total_size)as decimal(3,1))
from sysibmadm.snapstorage_paths

Unnamed[1]
----------
      10.0

That is not correct, 74434565120 *100 / 692060160000 = 10.75... What am I doing 
wrong here?
Thanks for any help in advance!
Kind regards,
