Implementation

@override
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);
