Fix AS::NumberHelper results with large precisions
before:
ActiveSupport::NumberHelper.number_to_rounded '3.14159', precision: 50
=> "3.14158999999999988261834005243144929409027099609375"
after:
ActiveSupport::NumberHelper.number_to_rounded '3.14159', precision: 50
=> "3.14159000000000000000000000000000000000000000000000"
