funcint64ToIntP(p *int64) *int{ifp ==nil {returnnil } i :=int(*p)return&i } 以上,今天遇到的时候需要类型强转,记录一下
string := strconv.Itoa(int) int→int64 int64_ := int64(int) int64→string string := strconv.FormatInt(int64,10) int→float float := float32(int) float := float64(int) int→uint64 uint64 := uint64(int) float→string string := strconv.FormatFloat(float64,'E',-1,64) string ...
使用int(值) 最后编辑于:2017.12.03 02:53:59

int64, err := strconv.ParseInt(string, 10, 64) #int到string string:=strconv.Itoa(int) #int64到string string:=strconv.FormatInt(int64,10) #int到int64,把int先转成字符串再转成int64,返回带err参数的需要忽略掉 s := strconv.Itoa(int) ...
总结了golang中字符串和各种int类型之间的相互转换方式: 转自:地鼠文档:wen.topgoer.com string转成int: int, err := strconv.Atoi(string) string转成int64: int64, err := strconv.ParseInt(string,10,64) string转float float,_ = strconv.ParseFloat(string,64) ...
intN,err:=strconv.Atoi(string) string 转int64 s:="15"// 字符串, 进制, 位int64N,err:=strconv.ParseInt(s,10,64)// 15 int 转 string varnintn=15str:=strconv.Itoa(n)// 输出 "15"//或str1:=strconv.FormatInt(int64(n),10)// 输出 "15" ...
