Is there any way to print a particular bit of a digit after

That can be easily done with substr y sprintf, this would take the
second bit of 7 written in base 2:
% perl -wle 'print substr sprintf("%b", 7), -2, 1'
1
That's quite readable, but if efficiency is an issue then pack/unpack
might be better, it had to be measured in any case.
