Msaccess_utilities.convert -- what's it for?

Question

Hi all,
I'm using SQL Developer 1.2.1.3213 with extension "Oracle Migration Workbench - MS Access" version 10.2.0.32.13
When I convert a query that uses CLNG in Access, it seems to be half-translated in the Oracle SQL to a call to the msaccess_utilities.convert function : the syntax is changed but the CLNG function name is not updated.
This causes the CREATE OR REPLACE VIEW function to fail when running the script into my Oracle database (10g XE)
Three questions on this:
1) Is this intentional?
2) Is there a switch or something I'm missing to make it use the convert function?
3) Why is the function there in the first place - the SQL does nothing?
Access SQL:
SELECT DISTINCTROW [Order Details].[Order ID], Sum(CLng([Unit Price]*[Quantity]*(1-[Discount])*100)/100) AS Subtotal
FROM [Order Details]
GROUP BY [Order Details].[Order ID];
Migration workbench sql
SELECT DISTINCT Order_Details.Order_ID,
SUM(CLNG('NUMBER', Unit_Price * Quantity * (1 - Discount) * 100) / 100) Subtotal
FROM Order_Details
GROUP BY Order_Details.Order_ID
(You can see it's added 'NUMBER' for the destination data type (?) to the function call)
What I expected:
SELECT DISTINCT Order_Details.Order_ID,
SUM(msaccess_utilities.convert('NUMBER', Unit_Price * Quantity * (1 - Discount) * 100) / 100) Subtotal
FROM Order_Details
GROUP BY Order_Details.Order_ID
OR
SELECT DISTINCT Order_Details.Order_ID,
SUM( Unit_Price * Quantity * (1 - Discount) * 100) / 100 Subtotal
FROM Order_Details
GROUP BY Order_Details.Order_ID
Thanks
