MathF.Exp() Method in C# with Examples

In C#, Exp(Single) is a MathF class method which is used to return the e raised to the specified power. Here e is a mathematical constant whose value is approximately 2.71828.

Syntax: public static float Exp (float x);
Here, x is the required number of type System.Single which specifies a power.

Return Type: It returns a number e raised to the power x of type System.Single.

Note:

• If x is equal to NaN then the return value will be NaN.
• If x is equal to PositiveInfinity then the return value will be Infinity.
• If x is equal to NegativeInfinity then the return value will be 0.

Example 1:

// C# Program to illustrate the
// MathF.Exp(Single) Method
using System;

class Geeks {

    // Main Method
    public static void Main()
    {

        // using the method
        Console.WriteLine(MathF.Exp(7.0f));
        Console.WriteLine(MathF.Exp(458.95f));
        Console.WriteLine(MathF.Exp(9.487f));
        Console.WriteLine(MathF.Exp(0.00f));
    }
}

Output:

1096.633
Infinity
13187.18
1

Example 2:

// C# Program to illustrate the
// MathF.Exp(Single) Method by
// taking NaN, PositiveInfinity
// and NegativeInfinity]
using System;

class Geeks {

    // Main Method
    public static void Main()
    {

        // Taking NaN
        Console.WriteLine(MathF.Exp(Single.NaN));

        // Taking PositiveInfinity
        Console.WriteLine(MathF.Exp(Single.PositiveInfinity));

        // Taking NegativeInfinity
        Console.WriteLine(MathF.Exp(Single.NegativeInfinity));
    }
}

Output:

NaN
Infinity
0
