Why convert anything "to binary" first, if you can use
"$var & (1 << $bitp

Hello Praveena,
I recommend you to use pack and unpack function.
I believe you can use this to convert the digit to
binary and also extract the digit of your choice from
the result.
perldoc -f pack
type this command at your linux console if any to get
the help on pack.
