How to represent the return value of a function in Golang function documentation?

In the GoLang function documentation, the return value of the function can be expressed using the following syntax: func Foo() (output1 type1, output2 type2, ..., outputN typeN), where Foo is the function name and output1 to outputN are the return values. , type1 to typeN are the types of return values.

#How is the return value of a function represented in GoLang function documentation?

In the GoLang function document, we can use the following syntax to represent the return value of the function:

func Foo() (output1 type1, output2 type2, ..., outputN typeN)

Where:

• Foo is The name of the function.
• output1, output2, ..., outputN is the return value of the function.
• type1, type2, ..., typeN is the type of the return value.

Practical case

Let’s look at an example function calculateSumAndAverage, which calculates the sum and average of a given slice:

// calculateSumAndAverage 计算给定切片中的和和平均值
func calculateSumAndAverage(numbers []int) (sum int, average float64) {
    // 计算和
    for _, number := range numbers {
        sum += number
    }

    // 计算平均值
    average = float64(sum) / float64(len(numbers))

    // 返回和和平均值
    return
}

In this function documentation, we use the following syntax to represent return values:

func calculateSumAndAverage(numbers []int) (sum int, average float64)

This means that the function returns two values: a sum of type int and An average of type float64.
