Bug #7969: Integer binary_op Float operations doesn't use coercion

I'm trying to override #coerce method on Float. But I found that redefining Float#coerce makes no changes in behavior of code: 1 + 2.0
class Float
  def coerce(other)
    [2, 2]
  end
end
puts 1+2.0 # ==> 3.0 while result should be 4.

Is it done due to perfomance considerations or it's just a bug? If it's intended is it a spec or realization specific feature?
