Golang的坑

https://i6448038.github.io/2017/07/28/GolangDetails/

new(type)不爲nil
fmt.Println(new(int)==nil) # false
var i *int
fmt.Println(i==nil) # true

一個包裏可以有多個init函數,多個init函數的調用順序 https://golang.org/ref/spec#Program_initialization_and_execution

猜猜下面的代碼輸出爲多少?
package main

import "fmt"
import "strconv"

func main() {
    div,_ := strconv.ParseFloat("0", 64)
    a := 37.2-float64(int(3/div))*150
    x:=fmt.Sprintf("%f", a)
    fmt.Println(x)   // 1383505805528216371200.000000
}
