Go类型转换

1.string转int

#string到int
int,err:=strconv.Atoi(string)
#string到int64
int64, err := strconv.ParseInt(string, 10, 64)

2.int转string

#int到string
string:=strconv.Itoa(int)
#int64到string
string:=strconv.FormatInt(int64,10)

3.string转float

#string到float64
float,err := strconv.ParseFloat(string,64)

#string到float32
float,err := strconv.ParseFloat(string,32)

4.float转string

#float到string
string := strconv.FormatFloat(float32,'E',-1,32)
string := strconv.FormatFloat(float64,'E',-1,64)

5.float转int

var x float64 = 6.9
    y := int64(x)

6.int转float

var i int64 = 9
i2f = float64(i)
