Case Statment Need Rounded

I have this case statement below it is for an access fee. My problem that I am having is that now I am getting a number that is huge. Example, 8.2350000000. I need this to be rounded up and numbers srinked to 8.24, how can I add that in my case statement below? Please help if you can.

Thanks



CASE clm_att1
WHEN 'NG' THEN CASE clm_h30 WHEN 0 THEN cast(clm_sppo as decimal(12,2))*(cast(clio_fee04 as decimal (12,2))/100)
ELSE cast(clm_H30 as decimal(12,2))*(cast(clio_fee04 as decimal (12,2))/100)
END
WHEN 'NA' THEN '0.00'

WHEN 'AF' THEN CASE clm_h30 WHEN 0 THEN cast(clm_sppo as decimal(12,2))*(cast(clio_fee04 as decimal (12,2))/100)
ELSE cast(clm_H30 as decimal(12,2))*(cast(clio_fee04 as decimal (12,2))/100)*.65
END

ELSE Null
END AS AccessFeeFinal,
