Subtract arrays having different FillValues

Dear NCL-users,

I want to subtract one array (x0) from another (x), both having same dimensions (lat,lon) but different FillValues.
So, I use assignFillValue(x0,x)
and then x(:,:) = (/ x(:,:) - x0(:,:) /)

But afterward when I am plotting the variable x(:,:), it shows unrealistic high values at those places where x0 contains missing value.
How can I solve this problem?
Is there any another way to subtract the arrays with FillValues?

Thanks in advance.

Best wishes,
