the final value should be a binary value(datatype) not a string of
binary digits.
eg:- if we do $a=0b."100" this becomes a string and when we take
the length($a) it gives us the size in bytes of a integer (here it would
be 4 bytes)
but if we do $a=0b100 its a binary value so length($a)
gives us the the size in bytes (so length would be 1 byte)
Consider
$a=0b100;
$b=0b."100";
print length($a)."\n"; #gives 1
print length($b); # gives 4
But if we do this
print length(pack ("b*","100010111")); this gives length 2 as there are 9
bits here ...
