我试了下，的确有这个问题。看了下代码 getDecimalValue这个方法里的decimalValue.toNumber()操作导致的数值变化，可以配置stringMode: true，这样就不会出现以上问题。

const getDecimalValue = (stringMode: boolean, decimalValue: DecimalClass) => {
  if (stringMode || decimalValue.isEmpty()) {
    return decimalValue.toString();
  }

  return decimalValue.toNumber(); // 这个方法会把 11111111111111111 转换为 11111111111111112
};
