2's complement negative and 10 binary digits

hi,
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.

2) DEC2BIN and BIN2DEC support of more than 10 binary digits, see:
