(2) Add to F&O Section 17.1.1, "If the resulting value is too large or small to be accurately represented by the implementation, it is handled as a numeric overflow or underflow as defined in F&O Section 6.2." Since you participated in this discussion, I will consider this comment to be closed. Regards, Don Chamberlin
