Why do the following not work (in Mathematica 7)?
2^^ # & /@ {1000, 1101}
and
2^^ # & @ 1101
This does work:
2^^1101
giving, as expected:
(*13*)
(This also works:
BaseForm[#, 2] & /@ {13, 14}
)
See here for further information ("Digits in numbers")
2^^ 1101
doesn't work either, which already is a strong hint that one shouldn't expect2^^ # &
to work. $\endgroup$
