abst2 = (AbstInt.new * 2).object # 2の倍数
abst3 = (AbstInt.new * 3).object # 3の倍数
abst2 % 2 #=> 0
abst3 % 3 #=> 0
abst2 % 3 #=> AbstInt::MultiResultError
(abst2 + 1) % 2 #=> 1
abst2_and_3 = ((AbstInt.new * 2) & (AbstInt.new * 3)).object # 2の倍数かつ3の倍数
abst2_and_3 % 6 #=> 0
abst2_and_3 % 2 #=> 0
abst2_and_3 % 3 #=> 0
not_abst3 = (AbstInt.new * 3).not.object # 3の倍数でない
not_abst3 % 3 #=> 1 or 2 を表現するオブジェクト
not_abst3 % 3 == 0 #=> false
not_abst3 % 3 == 1 #=> AbstInt::MultiResultError
