Today, I will show you how do I convert string to float in golang, as above mentioned I’m going to use ParseFloat() way.

The strconv package provide ParseFloat() method.

Let’s start our Golang convert string to float example

Convert whole string into float example

package main

import (
	"fmt"
	"reflect"
	"strconv"
)

func main() {
	s := "7.86"
	f, err := strconv.ParseFloat(s, 8)
	fmt.Println(f, err, reflect.TypeOf(f))
}
