Simple Q: bit string -> integer

Ruby
1

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)?

Yes, thanks a bunch. For some reason, #to_i was the
last place I thought to look.

“10010000”.to_i(2)

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

But what’s “num”?

“num” as in my brain is “numb” from staring at 1’s and 0’s.
