Bug #12414: FloatDomainError in infinite Range#include? for certain BigDecimals

[RubyBugs (A Nonymous)]

What I did

require 'bigdecimal'

r = 0.04...(Float::INFINITY)
n = BigDecimal.new('0.13E0')
r.include?(n.to_f)
r.include?(n)

What I expected

true
true

What happens instead

true
FloatDomainError: Infinity
	from (irb):19:in `to_r'
	from (irb):19:in `<=>'
	from (irb):19:in `include?'
	from (irb):19
	from /Users/msiegel/.rvm/rubies/ruby-2.2.3/bin/irb:15:in `<main>'

Workaround

To workaround, I am calling #to_f on the BigDecimal before submitting it to the Range#include?

Note that this exception only occurs for certain BigDecimal values, not for all.
