toString method

Implementation

@override
String toString() {
  if (_scale == 0) {
    return _unscaledValue.toString();
  }

  String unscaledStr = _unscaledValue.abs().toString();
  bool isNegative = _unscaledValue.isNegative;

  if (unscaledStr.length <= _scale) {
    // Add leading zeros
    String zeros = '0' * (_scale - unscaledStr.length + 1);
    unscaledStr = zeros + unscaledStr;
  }

  int insertPos = unscaledStr.length - _scale;
  String result = '${unscaledStr.substring(0, insertPos)}.${unscaledStr.substring(insertPos)}';

  return isNegative ? '-$result' : result;
}
