# 计算与汇率换算

### 四则计算

* 打开主窗口，直接输入四则运算公式即可计算
* 回车可以复制结果
* 输入 =  可以将结果带入主搜索框

### 汇率换算

HapiGo 支持实时汇率换算，但此结果仅供参考，无法作为投资依据。

打开主窗口，输入金额（如：$100），HapiGo 会自动给出人民币结果。同样的，如果输入 ￥100，HapiGo 也会计算出美元结果。应用默认设定人民币和美元的互换。

如果你希望得到其他货币的兑换结果，可以在金额后面输入 >，此时可以搜索任意货币进行换算。

#### 货币格式

在上面的介绍中，我们讲到输入货币以及搜索货币，所以有必要介绍一下 HapiGo 支持的货币格式。以下是 6 种我们支持的格式：

1. 货币符号+数字：￥100/100￥
2. 货币代码+数字：CNY100/100CNY
3. 国家中文名+数字（支持拼音）：中国100/100中国
4. 国家英文名+数字：China100/100China
5. 货币名称+数字（支持拼音）：人民币100/100人民币
6. 货币俗称+数字（支持拼音）：100元/元100/100块/块100/RMB100/100RMB

所以，上文当需要将人民币转成日元时：输入 cny100> ，然后可以用日元、日本、riben、japan、jpy 等方式来搜索目标货币。
