Go语言实现十进制转换成二、八、十六进制

package mainimport ("errors""fmt""strconv"
)func DecConvertToX(n, num int) (string,error) {
    if n < 0 {
    return strconv.Itoa(n),errors.New("只支持正整数")}if num != 2 && num != 8 && num != 16 {
    return strconv.Itoa(n),errors.New("只支持二、八、十六进制的转换")}result := ""h:=map[int]string{
    0:"0",1:"1",2:"2",3:"3",4:"4",5:"5",6:"6",7:"7",8:"8",9:"9",10:"A",11:"B",12:"C",13:"D",14:"E",15:"F",}for ; n > 0; n /= num {
    lsb := h[n % num]result = lsb + result}return result,nil
}
func main() {
    fmt.Println(DecConvertToX(26, 2))fmt.Println(DecConvertToX(26, 8))fmt.Println(DecConvertToX(26, 16))
}
