go中已經(jīng)實(shí)現(xiàn)了int->bin的轉(zhuǎn)化函數(shù)，我這里只是化過(guò)程邏輯的實(shí)現(xiàn)，至于原理我就假設(shè)大家都知道了
package main
import (
"fmt"
"strconv"
)
//bin表示轉(zhuǎn)化后的位數(shù)
func convertToBin(n int,bin int) string{
var b string
switch {
case n==0:
for i:=0;ibin;i++{
b+="0"
}
case n>0:
//strcov.Itoa 將 1 轉(zhuǎn)為 "1" , string(1)直接轉(zhuǎn)為assic碼
for ; n>0;n/=2{
b=strconv.Itoa(n%2)+b
}
//加0
j:=bin-len(b)
for i:=0;ij;i++{
b="0"+b
}
case n0:
n=n*-1
// fmt.Println("變?yōu)檎麛?shù)：",n)
s:=convertToBin(n,bin)
// fmt.Println("bin:",s)
//取反
for i:=0;ilen(s);i++{
if s[i:i+1]=="1"{
b+="0"
}else{
b+="1"
}
}
// fmt.Println("~bin :",b)
//轉(zhuǎn)化為整形，之后加1 這里必須要64，否則在轉(zhuǎn)化過(guò)程中可能會(huì)超出范圍
n,err :=strconv.ParseInt(b,2,64)
if err!=nil{
fmt.Println(err)
}
//轉(zhuǎn)為bin
//+1
b=convertToBin(int(n+1),bin)
}
return b
}
func main(){
fmt.Println(
convertToBin(5,8), //101
convertToBin(13,8), //1101
convertToBin(11111,8),
convertToBin(0,8),
convertToBin(1,8),
convertToBin(-5,8),
convertToBin(-11111,8),
)
}
以上所述是小編給大家介紹的go實(shí)現(xiàn)整型的二進(jìn)制轉(zhuǎn)化的方法,希望對(duì)大家有所幫助，如果大家有任何疑問(wèn)請(qǐng)給我留言，小編會(huì)及時(shí)回復(fù)大家的。在此也非常感謝大家對(duì)腳本之家網(wǎng)站的支持！
