  raise ArgumentError if str.empty?

  # These requirements seem a bit odd, but they're explicitly specified in the tests,
  # so we're obligated to keep them, for now. (This code was rewritten from a one-line
  # regex, due to security concerns with a polynomial regex being used on uncontrolled
  # data).

  str = str.chop if str.end_with?('.')
  return 0 if str.empty?

  result = Integer(str) rescue Float(object)

  integer = result.to_i
