Question

I have this select: select isnull(Pricea,0)-isnull(Priceb,0) as Differences
The format of the columns is decimal(12,4).
My question is: I could somehow to return decimals only if they are bigger than 0?
It seems to be confusing if the result will be for e.g 4.0000 so I would want to display the decimals only if they are bigger than 0. Is this possible?

When ceiling(Num) = floor(Num), the number is a integer

select case when ceiling(Num) = floor(Num) 
       then      CONVERT(varchar, CAST(Num as decimal))
       else      CONVERT(varchar, Num) 
       end
