Another thing I've always wondered about ;), as I use numerics far more than floats. From the docs: "However, arithmetic on numeric values is very slow compared to the integer types, or to the floating-point types" How much slower are numerics? And why (I guess it has to do with potentially different sizes)? Thanks, CSN __________________________________ Yahoo!
