/**
     * 将数值金额转换为中文大写金额
     * @param $amount float 金额(支持到分)
     * @param $type   int   补整类型,0:到角补整;1:到元补整
     * @return mixed 中文大写金额
     */
    public function convertAmountToCn($amount, $type = 1) {

        if(!is_numeric($amount)){
            return "要转换的金额只能为数字!";
        }

        // 金额为0,则直接输出"零元整"
        if($amount == 0) {
            return "零元整";
        }

        // 金额不能为负数
        if($amount < 0) {
            return "要转换的金额不能为负数!";
        }
