下面总结了go中常用的转换

#string到int

int,err:=strconv.Atoi(string)

#string到int64

int64, err := strconv.ParseInt(string, 10, 64)

#int到string

string:=strconv.Itoa(int)

#int64到string

string:=strconv.FormatInt(int64,10)

#string转float

s := "3.1415926535"v1, err := strconv.ParseFloat(v, 32)v2, err := strconv.ParseFloat(v, 64)

#float转string

v := 3.1415926535s1 := strconv.FormatFloat(v, 'E', -1, 32) //float32s2 := strconv.FormatFloat(v, 'E', -1, 64) //float64

#float截取小数点的位数

func Decimal(value float64) float64 {	value, _ = strconv.ParseFloat(fmt.Sprintf("%.2f", value), 64)	return value}

#判断map中的值是否存在

if _, ok := map[key]; ok {//存在}

#go中字符串的截取

res := strings.Split("heng,wowo", "，")

#go中数组转成字符串

proString := strings.Replace(strings.Trim(fmt.Sprint(ress), "[]"), " ", ",", -1)

#go中截取最后一位的字符串

pString = strings.Trim(pString, ",")

#go中计算字符串的长度

len([]rune(teacherInfoMap.Name))
