golang 转换Int，String

Posted 2021-05-24

// To decimal string:
n := int64(32)
str := strconv.FormatInt(n, 10)
fmt.Println(str)  // Prints "32"

// To hexadecimal string:
n := int64(32)
str := strconv.FormatInt(n, 16)
fmt.Println(str)  // Prints "20"

golang 字符串与int类型转换

一、字符串转int
func Atoi(s string) (int, error)

案例：

执行结果：
[email protected]  ~/Documents/project/src/test  go build int_string.go
[email protected]  ~/Documents/project/src/test  ./int_string
int, 100

二、int转字符串
func Itoa(i int) string

执行结果：
[email protected]  ~/Documents/project/src/test  go build int_string.go
[email protected]  ~/Documents/project/src/test  ./int_string
string,100
