Go基本数据类型与string类型互转

func Sprintf(format string, a ...interface{}) string

var num1 int = 99
str := fmt.Sprintf("%d", num1)

var num2 float64 = 23.456
str := fmt.Sprintf("%f", num2)

var b bool = true
str := fmt.Sprintf("%t", b)

var mychar byte = 'h'
str := fmt.Sprintf("%c", mychar)

func FormatBool(b bool) string
func FormatInt(i int64, base int) string
func FormatUint(i uint64, base int) string
func FormatFloat(f float64, fmt byte, prec, bitSize int) string
func Itoa(i int) string

var num1 int = 99
//第一个参数需转化为int64类型，第二个参数表示几进制
str := strconv.FormatInt(int64(num1), 10)
var num1 int = 99
str := strconv.Itoa(num1)

func FormatFloat(f float64, fmt byte, prec, bitSize int) string

var num2 float64 = 23.456
str := strconv.FormatFloat(num2, 'f', 3, 64)

var b bool = true
str := strconv.FormatBool(b)

var str string = "true"
b, _ := strconv.ParseBool(str)

func ParseInt(s string, base int, bitSize int) (i int64, err error)

var str string = "1234"
n, _ := strconv.ParseInt(str, 0, 64)

var str string = "1234"
num, _ := strconv.Atoi(str)

func ParseFloat(s string, bitSize int) (f float64, err error)

var str string = "123.456"
n, _ := strconv.ParseFloat(str, 64)
