How to convert a float to a string in Golang

In this tutorial, you will learn how you can convert a float value to a string value in golang

We will use the Sprintf function from the go fmt module to convert a float to a string.

Example

package main

import "fmt"

func main() {
    var a float64
    
    a = 2.456786

    var str string

    str = fmt.Sprintf("%v", a)

    fmt.Printf("string value of a float64 is %s \n", str)
}

Round float to 2 decimal places

We will use the above Sprintf function to round the value of float type to 2 decimal places and convert it to a string.

Example

package main

import "fmt"

func main() {
    var a float64
    
    a = 2.456786

    var str string

    str = fmt.Sprintf("%.2f", a)

    fmt.Printf("Round to 2 decimal places: %s \n", str)
}
