Simple Q: bit string -> integer

[Todd Benson]

Is there a simple way to induce a bit string into an
integer; for example, "10010000" into 144? And also,
to show a Fixnum in its different representations
(hex, num, binary)?

Try this

str = "10010000"
p str.to_i(2)
puts
p 255.to_s(16)
p 255.to_s(2)

144.to_s(16), 144.to_s(2)

But what's "num"?
