For Salesforce.com we where sending a null value (or setting the field to null) if the value of an existing record with a Double (Numeric) field was 0. This was leading to errors from SFDC in some situation - for example when updating prices in SFDC.
Now we send the value as 0 when updating a Double field.
This should make it possible to update e.g. UnitPrice on PriceEntry to 0.
