Declare @hardcurrency Table(Rate numeric(28,4))
insert @hardcurrency
select 25000.0000
union all
select 3.0825
union all
select 950000.0000

select rate,round(1/rate,4) as ExRate
from @hardcurrency

whenever im rounding to 4 its coming as:
0.00000000000000000000000000000
0.32440000000000000000000000000
0.00000000000000000000000000000

Expected output should be :
ExRate
0.00004
0.3244
0.000001

if i got the scale value which is > 0 from the beginning itself mean then round off to 4 else until i get the number(>0) i need to round off there.

you cant have variable scale value. You need to set based on available values the scale value you want and all values will be shown rounded based on it

[code]case when round(1/rate,4) <> 0
then convert(numeric(28,10), round(1/rate,4))
else convert(numeric(28,10), left(convert(varchar(max), 1/rate), patindex('%[1-9]%', convert(varchar(max), 1/rate))))
end
[/code]
