int integer to string--use Itoa()
The Itoa() function is used to convert int type data to the corresponding string type. The function signature is as follows.
func Itoa(i int) string
The sample code is as follows:
package main
import (
"fmt"
"strconv"
)
func main() {
num := 100
str := strconv.Itoa(num)
fmt.Printf("type:%T value:%#v\n", str, str)
}The running result is as follows:
type:string value:"100"
int integer to string--use FormatInt()
FormatInt() function is used to convert integer data into a specified base and return it in the form of a string. The function signature is as follows:
func FormatInt(i int64, base int) string
Among them, the parameter i must be of type int64, and the parameter base Must be between 2 and 36. Lowercase letters "a" to "z" will be used in the returned result to represent numbers greater than 10.
The sample code is as follows:
package main
import (
"fmt"
"strconv"
)
func main() {
var num int64 = 100
str := strconv.FormatInt(num, 10)
fmt.Printf("type:%T,value:%v\n ", str, str)
}The running results are as follows:
type:string,value:100
