Sorry, but I need a clarification on this. Spec says ""When unparsing a binary number (packed decimal or twos-complement) and excess precision is supplied in the Infoset no rounding occurs. It is a processing error."" Technically, precision is the number of digits, and trailing zeros are significant even after a decimal point. So is it a processing error if I supply an infoset decimal value of 123. 990 and a BDVP of 2? While this can be serialized to an integer, the original decimal has excess precision. Similarly for an infoset decimal value of 12300.0 and a BDVP of -2. This can be serialized to an integer, but the original decimal has excess precision. What this amounts to is whether we give a processing error a) whenever the infoset supplies excess precision, or b) only when the excess precision results in a decimal that can't be converted into an integer.

This is surely a processing error, because the spec states in section 13.7.1 "When unparsing a binary number (packed decimal or twos-complement) and excess precision is supplied in the Infoset no rounding occurs. It is a processing error."
