Golang : How to read float value from standard input ?

This is a continuation from previous tutorial on how to read integer value from standard input. For this tutorial, we will learn how to read float value from standard input. Below is the code to do that :

 package main

 import (
 "fmt"
 "strconv"
 )

 func main() {

 var f float64

 fmt.Println("Enter a float value : ")
 _, err := fmt.Scanf("%f", &f)

 if err != nil {
 fmt.Println(err)
 }

 fmt.Printf("You have entered : %f \n", f)

 fmt.Println("Alternative output ", strconv.FormatFloat(f, 'f', 6, 64))

 }
