How to convert int64 to string in go language

How to convert int64 to string in go language: 1. Create a go sample file; 2. Enter the code "i := int64(123)"; 3. Pass "s := strconv.FormatInt(i, 10 )" method to convert int64 to string.

The operating environment of this article: Windows7 system, Go1.11.2, Dell G3 computer.

int64 to string

i := int64(123)
s := strconv.FormatInt(i, 10)

The second parameter is the base number, optional 2~36

Note: For unsigned integer, you can use FormatUint (i uint64, base int)

PS: Go language string, int, int64 conversion to each other

//string到int 
int,err:=strconv.Atoi(string) 
//string到int64 
int64, err := strconv.ParseInt(string, 10, 64) 
//int到string 
string:=strconv.Itoa(int) 
//int64到string 
string:=strconv.FormatInt(int64,10)
//string到float32(float64)
float,err := strconv.ParseFloat(string,32/64)
//float到string
string := strconv.FormatFloat(float32, 'E', -1, 32)
string := strconv.FormatFloat(float64, 'E', -1, 64)
// 'b' (-ddddp±ddd，二进制指数)
// 'e' (-d.dddde±dd，十进制指数)
// 'E' (-d.ddddE±dd，十进制指数)
// 'f' (-ddd.dddd，没有指数)
// 'g' ('e':大指数，'f':其它情况)
// 'G' ('E':大指数，'f':其它情况)
