Converting Double to String in Various Programming Languages

double to string

In many programming languages, converting a double (or floating-point number) to a string is a common task. Here are examples in a few popular languages:

C++

#include <iostream>
#include <string>

int main() {
    double num = 123.456;
    std::string str = std::to_string(num);
    std::cout << "The string representation is: " << str << std::endl;
    return 0;
}

Python

num = 123.456
str_num = str(num)
print("The string representation is:", str_num)

Java

public class Main {
    public static void main(String[] args) {
        double num = 123.456;
        String str = Double.toString(num);
        System.out.println("The string representation is: " + str);
    }
}

JavaScript

let num = 123.456;
let str = num.toString();
console.log("The string representation is: " + str);

C#

using System;

class Program
{
    static void Main()
    {
        double num = 123.456;
        string str = num.ToString();
        Console.WriteLine("The string representation is: " + str);
    }
}

Ruby

num = 123.456
str = num.to_s
puts "The string representation is: #{str}"

Go

package main

import (
    "fmt"
    "strconv"
)

func main() {
    num := 123.456
    str := strconv.FormatFloat(num, 'f', -1, 64)
    fmt.Println("The string representation is:", str)
}

Swift

let num: Double = 123.456
let str = String(num)
print("The string representation is: \(str)")

Each of these examples demonstrates how to convert a double to a string in different programming languages. The specific method or function used can vary, but the concept remains the
