AG> Thanks Dan and Devon
If it interests you, those two responses illustrated the two "digitization"
approaches you outlined, respectively:
AG> the more common repeated integer division
DB> 10&#.^:_1
This phrase is (strictly) arithmetic, which is why I prefer it. (By the
way, you might get more use out of it if you spelled _1 as _1: , so you
will require parenthesis less often.)
AG> the Perl-like conversion to a string
AG> which is then split or "exploded"
DM> ".&>&.>":&.>nums
DM> +-+-+---+-----+-------+
DM> |0|1|1 1|1 0 1|1 2 3 4|
DM> +-+-+---+-----+-------+
Another way to phrase this is "."0@": (which formulation is supported by
special [fast] code [2] ).
But since we're talking about Jems today, let's try to find something a
little more lovely:
,.&.": 1000
1 0 0 0
Arie Groeneveld came up with it in [1] . It perfectly illustrates (actually
epitomizes) the Perl approach of projection into the string domain,
transformation, and return. Definitely a Jem.
