Go 类型转换

package main
import (
   "fmt"
   "strconv"
)
func main() {
   var i int = 10
   var f float64 = 6.44
   var str1 string = "101"
   var str2 string = "10.123"
   fmt.Println(float64(i))
   fmt.Println(int(f))
   newInt, _ := strconv.ParseInt(str1, 0, 64)
   fmt.Println(newInt)
   newfloat, _ := strconv.Parsefloat(str2, 64)
   fmt.Println(newfloat)
}
