How to use strconv.FormatUint() Function in Golang?
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:
// Golang program to illustrate // strconv.FormatUint() Function package main import ( "fmt" "strconv" ) func main() { // Finding the string representation // of given value in the given base // Using FormatUint() function fmt.Println(strconv.FormatUint(11, 2)) fmt.Println(strconv.FormatUint(24, 10)) } |
Output:
1011 24
Example 2:
// Golang program to illustrate // strconv.FormatUint() Function package main import ( "fmt" "strconv" ) func main() { // Finding the string representation // of given value in the given base // Using FormatUint() function 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
