# 07.02-回傳多個值

Go 語言的函式可以傳回多個值：

```go
func f() (int, int) {
    return 5, 6
}

func main() {
    x, y := f()
}
```

不過需要有三個改變：傳回值的型別要改成放多個型別，而且每個型別之間要使用 `,` 隔開，在 return 之後的傳回值也要調整，改成使用 `,` 將傳回值隔開。最後一點是，接收函式多個傳回值的變數會在函式的左邊（`:=` 或 `=`），並且一樣分別用 `,` 隔開。

通常需要傳回多個傳回值的時機是：需要同時傳回錯誤碼與結果（`x, err := f()`），或者是用一個布林值（boolean）來代表成功時 （`x, ok := f()`）。

## 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://go.netdpi.net/functions/return_multi_vals.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.
