## Introduction

C# is a powerful programming language that is used to create a wide variety of applications. It is a popular language for developing Windows applications, web applications, and mobile applications. One of the features of C# is the ability to display a variable with an exponential. This tutorial will explain how to display a variable with an exponential in C#. It will also provide some examples of how to use this feature.

## Solution

//Declare the variable

double number = 10.0;

//Display the variable with an exponential

Console.WriteLine(“{0:E}”, number);

you can use unicode code points:

**Superscript digits**

\u2070\u00b9\u00b2\u00b3\u2074\u2075\u2076\u2077\u2078\u2079

**Subscript digits**

U+2080 to U+2089

Example:

```
var superscriptstring = "C\u2074";
var subscriptstring = "C\u2081";
```

solved C# – I need to display a variable with an exponential [closed]

If you need to display a variable with an exponential in C#, you can use the `Math.Pow()`

method. This method takes two parameters, the base and the exponent, and returns the result of the calculation. For example, if you wanted to display the result of 2 to the power of 3, you would use the following code:

```
double result = Math.Pow(2, 3);
Console.WriteLine(result);
```

This would output the result of 8. You can also use the `Math.Exp()`

method to calculate the exponential of a number. This method takes a single parameter, the exponent, and returns the result of the calculation. For example, if you wanted to calculate the exponential of 3, you would use the following code:

```
double result = Math.Exp(3);
Console.WriteLine(result);
```

This would output the result of 20.08553692318766. Both of these methods are part of the System.Math class, so you will need to include the `using System;`

statement at the top of your code file in order to use them.
