是否有可能在Golang中返回Integer或Float的函数？

Question

I'd like to create a function which returns an integer value if a condition passes inside the function and a floating point number otherwise. How can I handle this with Go? Thank you!

Yes, it is possible. You just have to return it as a float:

func doStuff(flag bool) float32 {
    if flag {
        return 1.1
    }
    return 1
}

func main() {
    num1 := doStuff(true)
    num2 := doStuff(false)
    fmt.Println("Num1: ", num1)
    fmt.Println("Num2: ", num2)
}

The only thing that matters is how you format it for displaying.
