判断golang中的空浮点或整数值

nil

nil

这意味着您可以判断零值:

if foo == 0 {
  // it's a zero value
}

或者你要处理指针:

package main

import (
    "fmt"
)

func main() {
    var intPointer *int

    // To set the value use:
    // intValue := 3
    // intPointer = &intValue

    if intPointer == nil {
        fmt.Println("The variable is nil")
    } else {
        fmt.Printf("The variable is set to %v\n", *intPointer)
    }
}
