类型转换

package main
import (
    "fmt"
    "reflect"
    "strconv"
)
func main() {
    var intValue int = 97
    int32Value := int32(intValue)
    int64Value := int64(intValue)
    fmt.Println(int64Value, int32Value)
    //转换成数字对应的字符编号，如65-A,100-a
    s := string(int32Value)
    fmt.Println(s)
    //int转字符串
    ret := fmt.Sprintf("%d", int32Value)
    strconv.Itoa(int(int32Value))
    fmt.Println(reflect.TypeOf(ret))
    fmt.Printf("%#v %T", ret, ret)
    var stringValue string = "100"
    //字符串、进制数、类型：int,int8,int16,int32,int64
    strconv.ParseInt(stringValue, 10, 64)
    //字符串转int
    strconv.Atoi(stringValue)
    //字符串转bool
    strconv.ParseBool("true")
    //字符串转float
    strconv.ParseFloat("1.00",32)
