        ? throw _conversionException('.toDecimal()', results)
        : _isNotAcceptedType(results)
            ? [false]
            : results.first is bool
                ? [results.first == true ? 1 : 0]
                : results.first is num
                    ? [(results.first as num).toDouble()]
                    : double.tryParse(results.first as String) != null
                        ? [double.parse(results.first as String)]
                        : [];
