How to use ROUND( ) function to a nested case statement

[Albatross]

Hi There!
I wrote the below case statement. But it is not giving the required results. I WANT 93,855 BUT I'M GETTING 938.5566666666666666666 like this. 

(SELECT CASE (MAIN.RECEIPT+MAIN.ISSUE) WHEN 0 THEN 0.0 ELSE MAIN.AMOUNT/(MAIN.RECEIPT+MAIN.ISSUE) END)  AS UNITP

So I tried writing the nested case statement for the above line and it worked but in the output, I'm getting so many numbers after decimal. I want the number to round off and I have tried ROUND( ) as well it is throwing an error maybe I misplaced the function. Can anyone let me know how to use ROUND( ) in nested case statements? Thanks

CASE
	WHEN 
		case MSEG.SHKZG when 'S' then MSEG.MENGE else 0.0 end
		+
		case MSEG.SHKZG when 'H' then MSEG.MENGE else 0.0 end = 0
	THEN 0.00
ELSE
	CASE
		WHEN 
			CASE WHEN MSEG.DMBTR = 0 THEN 0 ELSE 0.00 END = 0
			AND 
			CASE WHEN MSEG.MENGE = 0 THEN 0 ELSE 0.00 END = 0
			AND
			case MSEG.SHKZG when 'S' then MSEG.MENGE else 0.0 end = 0
			AND
			case MSEG.SHKZG when 'H' then MSEG.MENGE else 0.0 end = 0
		THEN 0
	ELSE
			MSEG.DMBTR/
			(case MSEG.SHKZG when 'S' then MSEG.MENGE else 0.0 end
			+
			case MSEG.SHKZG when 'H' then MSEG.MENGE else 0.0 end)
	END
END
AS UNITP,

1) Is it ABAP, ABAP CDS or HANA CDS? 2) There are two questions in one, frst one: why it's multiplied by 10 (NO REASON, CHECK YOUR DATA AGAIN), second one: why it's not rounded. You should use CAST to type correctly your result.
