Go language provides inbuilt support to implement conversions to and from string representations of basic data types by strconv Package. This package provides a FormatUint() function which is used to return the string representation of x in the given base, i.e., 2 <= base <= 36.
Here, the result uses the lower-case letters ‘a’ to ‘z’ for digit values which is greater than equals to 10. To access FormatUint() function you need to import strconv Package in your program with the help of import keyword.
Syntax:
func FormatUint(x uint64, base int) string
Parameter: This function takes two parameters, i.e., x and base.
Return value: This function returns the string representation of x in the given base, i.e., 2 <= base <= 36.
Example 1:
package main
import (
"fmt"
"strconv"
)
func main() {
fmt.Println(strconv.FormatUint(11, 2))
fmt.Println(strconv.FormatUint(24, 10))
}
|
Output:
1011
24
Example 2:
package main
import (
"fmt"
"strconv"
)
func main() {
val1 := uint64(25)
res1 := strconv.FormatUint(val1, 2)
fmt.Printf( "Result 1: %v" , res1)
fmt.Printf( "\nType 1: %T" , res1)
val2 := uint64(20)
res2 := strconv.FormatUint(val2, 16)
fmt.Printf( "\nResult 2: %v" , res2)
fmt.Printf( "\nType 2: %T" , res2)
}
|
Output:
Result 1: 11001
Type 1: string
Result 2: 14
Type 2: string
