# 多币种与汇率

多币种可以用于账单、账户、预算、投资和统计。账户和账单始终保留原货币，汇率用于跨币种汇总和显示。

## 管理货币和汇率

打开 **货币与汇率**，查看或编辑不同货币之间的汇率。

{% hint style="info" %}
账户和账单始终保留原货币；修改汇率只影响跨币种换算和汇总显示，不会改写原始金额。
{% endhint %}

## 显示规则

| 位置    | 显示方式         |
| ----- | ------------ |
| 账户行   | 显示账户自己的货币和余额 |
| 资产顶部  | 换算为当前统计货币后汇总 |
| 父子账户  | 子账户先换算为主账户货币 |
| 统计与预算 | 按页面选择的货币显示   |
| 换汇账单  | 分别保留转出和转入金额  |

## 记录换汇

1. 新增账单时选择 **换汇**。
2. 选择转出账户和转入账户。
3. 填写两侧金额或本次汇率。
4. 保存后，两个账户余额会同时更新。

## 净资产换算

资产页面按当前筛选范围计算资产、负债和净资产。账户行、顶部汇总和当前净资产都只计算截至当前时间已经发生的账单；未来账单会在到达账单时间后影响余额。净资产走势会按账单日期回放账户余额，并应用账本筛选、账户统计设置和对应日期的汇率。

{% hint style="warning" %}
账户行与页面汇总不同时，先检查统计货币、账本筛选、父子账户、汇率和账户是否被排除统计。
{% endhint %}

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.daak2.com/zh-cn/ji-zhang/currency.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
