In go language, string(int) will treat int as the Unicode value of UTF-8 and convert it into corresponding characters. The standard library strconv is specially used to implement the mutual conversion of basic data types and their string representations.
package main
import (
"fmt"
"strconv"
)
func main() {
// 64-bit integer i := int64(123)
// Integral to UTF-8 characters s := string(i)
(s) // {
// Integer to string s1 := (i, 10)
(s1) // 123
}package main
import (
"fmt"
"strconv"
)
func main() {
//string to int s := "1"
i, _ := (s)
(i)
("%T\r\n", i)
//string to int64 s64 := "64"
i64, _ := (s64, 10, 64)
(i64)
("%T\r\n", i64)
//int to string s = (i)
(s)
//int64 to string s64 = (i64, 10)
(s64)
//string to float32(float64) sfloat := "1.23"
f32, _ := (sfloat, 32/64)
(f32) // 1.23
("%T\r\n", f32) // float64
// float to string sf32 := (f32, 'E', -1, 32)
(sf32)
f64 := float64(100.23456) // 1.23E+00
sf64 := (f64, 'E', -1, 64)
(sf64) // 1.0023456E+02
// 'b' (-ddddp±ddd, binary index) // 'e' (-±dd, decimal index) // 'E' (-±dd, decimal index) // 'f' (-, no index) // 'g' ('e':big index, 'f': other situations) // 'G' ('E':Big Index, 'f':Other Situation)}refer to
