Go语言十进制转二进制字符串

代码Demo

func Test_2(t *testing.T) {
        // 方法一
        fmt.Println(DecToBin(5))
        // 方法二：导入包"github.com/imroc/biu"
        fmt.Println(biu.ToBinaryString(uint8(5)))
}

// 原理：除2取模是最低位
func DecToBin(n int) string {
        result := ""

        if n == 0 {
                return "0"
        }

        for ;n > 0;n /= 2 {
                lsb := n % 2
                result = strconv.Itoa(lsb) + result
        }

        return result
}
