Feature #10641: Introduce Fixnum#finite? and Bignum#finite?

Hello,
I propose to introduce Fixnum#finite? and Bignum#finite? methods. Use case for this is following:

Interval = Struct.new(:from, :to) do
  def finite?
    from.finite? && to.finite?
  end
end

For now this works:

Interval.new(1.5, 1000.0).finite?
Interval.new(1.5, Float::INFINITY).finite?

But this fails due to absence of Fixnum#finite?:

Interval.new(1, 3).finite?
Interval.new(1, Float::INFINITY).finite?

It looks natural that Fixnum#finite? should always return true. I didn't worked extensively with Bignum-s, but probably Bignum#finite? should also always be true.

It looks, feature request can be closed (implemented in #12039)

Yes it is. Closing.

Second try.
