Description

Reading #3429 again, I noticed a related bug (and by the way, thank you nobu for solving that bug!):

I wrote:
"Also, while doing some tests about this I noticed that "bignum == Float::INFINITY" [...], while it should not, as it is always false."

I did not notice it to hang anymore, but the result of #== is asymmetrical:

irb for ruby 2.0.0 r35779
> n=2**7830457;nil
=> nil
> n == Float::INFINITY
=> false
> Float::INFINITY == n
=> true

I think a Bignum is never infinite.
