## Overview

The **`Double.MaxValue`** in C# is a `Double` field that represents the largest possible value of `Double`. It is constant and read-only. This means it cannot be changed.

## Syntax

public const double MaxValue = 1.7976931348623157E+308;

## Parameters

None. It is only invoked on the `Double` object.

## Return value

The field `Double.MaxValue` returns the value `1.7976931348623157E+308`.

## Code example




// use System
using System;

// create class
class DoubleMaxValue
{   
    // main method
    static void Main()
    {
      // print the field value
      Console.WriteLine(Double.MaxValue);
      // perform arithmetic operations
      double d1 = Double.MaxValue + 323.323;

      // print results
      Console.WriteLine(d1);
    }
}

## Explanation
* **Line 11**: We print the value of the `Double.MaxValue` field to the console.
* **Line 13**: We perform some arithmetic operations with the field.
* **Line 16**: We print the results.

As we can see, the results for the `double` variable are not greater than the `Double.MaxValue` field.
