List execute(List results, Map<String, dynamic> passed) {
  final executedValue = value.execute(results.toList(), passed);
  return results.isEmpty
      ? []
      : results.length > 1
      ? throw _wrongLength('.log()', results)
      : executedValue.length > 1
      ? throw _wrongArgLength('log()', executedValue)
      : executedValue.first is num && results.first is num
      ? [log(results.first as num) / log(executedValue.first as num)]
      : throw _wrongTypes('log()', results, executedValue);
}
