Different Ways to Convert an Integer Variable to String in Golang Last Updated : 28 Apr, 2025 Comments Improve Suggest changes Like Article Like Report Integer variable cannot be directly convert into String variable. In order to convert string to integer type in Golang , you have store value of integer variable as string in string variable. For this, we are using strconv and fmt package functions. 1. Itoa() Function: The Itoa stands for Integer to ASCII and returns the string representation of integer with base 10. Syntax: func Itoa(i int) string Example : Convert an integer variable into String using strconv.Itoa() function. Go // Go program to illustrate // How to convert integer // variable into String package main import ( "fmt" "strconv" ) //Main Function func main() { i := 32 s := strconv.Itoa(i) fmt.Printf("Type : %T \nValue : %v\n", s, s) } Output: Type : string Value : 32 2. FormatInt() Function: The FormatInt is used to represents the string of integer value with base [2,36]. The result uses the lower-case letters 'a' to 'z' for digit values >= 10. Syntax: func FormatInt(i int64, base int) string Example : Convert an integer variable into String using strconv.FormatInt() function. Go // Go program to illustrate // How to convert integer // variable into String package main import ( "fmt" "strconv" ) //Main Function func main() { i := -32 s := strconv.FormatInt(int64(i) , 7) fmt.Printf("Type : %T \nValue : %v\n", s, s) } Output: Type : string Value : -44 3. FormatUint() Function: The FormatUint is used to represents the string of integer value with base [2,36]. The result uses the lower-case letters 'a' to 'z' for digit values >= 10. It is similar to FormatInt but the difference is that uint64 is the type of integer value. Syntax: func FormatUint(i uint64, base int) string Example : Convert an integer variable into String using strconv.FormatUint() function. Go // Go program to illustrate // How to convert integer // variable into String package main import ( "fmt" "strconv" ) //Main Function func main() { i := 32 s := strconv.FormatUint(uint64(i) , 7) fmt.Printf("Type : %T \nValue : %v\n", s, s) } Output: Type : string Value : 44 4. Sprintf() Function: The Sprintf is used to represents the string of integer value by formatting according to a format specifier and returns the resulting string. Syntax: func Sprintf(format string, a ...interface{}) string Example : Convert an integer variable into String using fmt.Sprintf() function. Go // Go program to illustrate // How to convert integer // variable into String package main import ( "fmt" ) //Main Function func main() { i := 32 s := fmt.Sprintf("%d", i) fmt.Printf("Type : %T \nValue : %v\n", s, s) } Output: Type : string Value : 32 Comment More infoAdvertise with us Next Article Different Ways to Convert an Integer Variable to String in Golang S SHUBHAMSINGH10 Follow Improve Article Tags : Go Language Similar Reads Go Tutorial Go or you say Golang is a procedural and statically typed programming language having the syntax similar to C programming language.
