# 折扣

## **概述**

如果提取的表格包含 **折扣** 或 **折扣百分比** 列，**DocBits** 会在处理过程中，自动将相应的折扣应用于单价，详见[**采购订单匹配界面**](/chinese/zui-zhong-yong-hu-yu-he-zuo-huo-ban/end-user-section/purchase-order-matching.md)。

## 例外情况

使用多重匹配功能时，不会自动应用折扣。有关多重匹配功能的更多信息，请参阅[此处](/chinese/zui-zhong-yong-hu-yu-he-zuo-huo-ban/end-user-section/purchase-order-matching.md#multi-matches)。

## 折扣计算

存在 **折扣** 时，折后单价的计算方式为从单价中减去折扣金额：

```
UNIT_PRICE_DISCOUNTED = UNIT_PRICE - DISCOUNT
```

## 折扣百分比计算

存在 **折扣百分比** 时，折后单价使用以下公式计算：

```
UNIT_PRICE_DISCOUNTED = UNIT_PRICE * (1 - DISCOUNT_PERCENT / 100)
```

## 舍入

所有折后单价结果均舍入到小数点后四位，以确保后续处理的一致性。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.docbits.com/chinese/zui-zhong-yong-hu-yu-he-zuo-huo-ban/end-user-section/purchase-order-matching/discounts.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
