Operating with binary numbers

Hello,

I found that you can represent binary numbers in Mathematica with this:

 binary = 2^^110110101010111010
223930

And BaseForm[binary, 10] returns the number in decimal form
  223930

I'd like to know if is there some function to test if a given bit of the 
binary number is on, and to do operations like "shifting" the binary number. 
I looked at the help but can't find anything.

I use Mathematica 5.0 on Windows XP.

Thanks.
