C# Math - Exp() Method

The C# Exp() method returns e raised to the power of specified number, i.e., e^x. Please note that e is the base of the natural system of logarithms, and its value is approximately 2.718282. In special cases it returns the following:

If the argument is NaN, the method returns NaN.
If the argument is positive infinity, the method returns positive infinity.
If the argument is negative infinity, the method returns zero.

Syntax

public static double Exp (double x);

Parameters

`x`	Specify the Exponent of e.

Return Value

Returns e raised to the power of specified number.

Example:

In the example below, Exp() method is used to calculate e raised to the power of specified number.

using System;

class MyProgram {
  static void Main(string[] args) {
    Console.WriteLine("Math.Exp(-2) = "
                      + Math.Exp(-2));
    Console.WriteLine("Math.Exp(-1) = "
                      + Math.Exp(-1));
    Console.WriteLine("Math.Exp(0) = "
                      + Math.Exp(0));
    Console.WriteLine("Math.Exp(1) = "
                      + Math.Exp(1));
    Console.WriteLine("Math.Exp(2) = "
                      + Math.Exp(2));
    Console.WriteLine("Math.Exp(Double.NaN) = "
                      + Math.Exp(Double.NaN));
    Console.WriteLine("Math.Exp(Double.NegativeInfinity) = "
                      + Math.Exp(Double.NegativeInfinity));
    Console.WriteLine("Math.Exp(Double.PositiveInfinity) = "
                      + Math.Exp(Double.PositiveInfinity));
  }
}

The output of the above code will be:

Math.Exp(-2) = 0.135335283236613
Math.Exp(-1) = 0.367879441171442
Math.Exp(0) = 1
Math.Exp(1) = 2.71828182845905
Math.Exp(2) = 7.38905609893065
Math.Exp(Double.NaN) = NaN
Math.Exp(Double.NegativeInfinity) = 0
Math.Exp(Double.PositiveInfinity) = Infinity
