From the post:

this just to be sure the RFEs for ODv1.3 was tracked and so can be discussed
and maybe added.
The RFEs are:

1) a modification to BASE(), to support two's complement negative binary
numbers.
Use the optional 3th parameter: 'Integer MinimumLength' to specify the bit
size of the machine word for negative numbers.
