Golang : convert(cast) string to float value

To convert or cast a string to float value, just use the strconv.ParseFloat() function. Below is the code example to demonstrate how to convert string to float64 value.

 package main

 import (
 "fmt"
 "strconv"
 )

 func main() {
 var floatvalue float64

 floatvalue, _ = strconv.ParseFloat("123.456", 64)

 fmt.Println(floatvalue)
 }
