I have below SQL that returns the result, but I want the price to rounded to 6 decimal places.

```
select opt.blo,
  opt.premiumcurrency,
     case
      when opt.structurename is not null then opt.basemarketprice /100
        when pct = 1 then opt.basemarketprice /100
        when pct = 2 then opt.termmarketprice / opt.notional
        when opt.notionalcurrency = opt.premiumcurrency  then opt.basemarketprice /100
        else opt.termmarketpricepercent /100
    end as round(price,6)
from interafce opt

```

When I add below it gives me error

**ORA-00923: FROM keyword not found where** 

Thanks for your help.
