D2C function

+-----------------------------------------------------------------------------+
| D2C(whole-number, [length])                                                 |
+-----------------------------------------------------------------------------+

Returns a string that is the binary representation of the specified
whole-number.  If the length is not specified, the whole-number must be
non-negative, and the result will be stripped of any leading '00'x characters.
If the length is specified, the result will be sign-extended to the left to
that length, or truncated on the left if the length is shorter than the result.

Examples:

    D2C(9)      == '09'x
    D2C(l29)    == '81'x
    D2C(l29,l)  == '81'x
    D2C(l29,2)  == '0081'x
    D2C(257,1)  == '01'x
    D2C(-127,l) == '81'x
    D2C(-127,2) == 'FF81'x
    D2C(-l,4)   == 'FFFFFFFF'x
    D2C(l2,0)   == ''
