I don't know why you'd need to convert it to decimal. The number
format of 0b01100010 works just fine as literals. If you are reading
the data instead, pack "N", unpack "B*", $value works pretty well to
convert it into a number (NOT decimal!).
Probably what you want is:
printf "%b\n", 0b01100010 & 0b11001001;
Similarly, "|" for "or", "^" for "xor", and "+" for add.
