Converting Integer to binary string

ruby-talk
1

Hello all,

I tried searching the list for this, but didn't see the answer
anywhere. A lot of people trying to do the opposite, but.. :slight_smile:

I'd like to convert the Integer 585 to the string "1001001001"

I see from the docs for Fixnum#[] that I could hack something together:

30.downto(0) { |i| print 585[i] }

But sometimes you just *know* there's a better way...

Thanks in advance,
-Harold
