I Forgot that I'm asking a bunch of CS geeks a 
question about "binary"... I mean "bianry" as in 
the base 2 representation of numbers... One is one 
is one, but one can be represented in different 
bases and still be one... get it?

How do I pass the binary representation of a 
number to a function???
