Optional parameter to digits() / binary() functions for fixed vector size output

[Jérôme Raulin <jerome@raulinfoissac.fr>]

Dear all,

Would it be possible to add an optional parameter ‘len’ to ‘digits()’ and ‘binary()’ functions in order to pad the output on the left with zeros to give a vector of at least length ‘len’.

It is sometime useful to iterate over all representations of b^n-1 in base b (usually in base 2) and it would be useful to have digits(1, b, n) to return [0, 0, …, 1] instead of [1].

Thanks very much.

Regards.

Jerome.
