C# | Math.Exp() Method
In C#, Exp() is a Math 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. Exp() is the inverse of Log().
Syntax:
public static double Exp (double num);
Parameter:
num: It is the required number of type System.Double which specifies a power.
Return Type: It returns a number e raised to the power num of type System.Double.
Note:
- If num is equal to NaN then the return value will be NaN.
- If num is equal to PositiveInfinity then the return value will be Infinity.
- If num is equal to NegativeInfinity then the return value will be 0.
Example 1:
// C# Program to illustrate the // Math.Exp(Double) Method using System; class Geeks { // Main Method public static void Main() { // using the method Console.WriteLine(Math.Exp(10.0)); Console.WriteLine(Math.Exp(15.57)); Console.WriteLine(Math.Exp(529.548)); Console.WriteLine(Math.Exp(0.00)); } } |

Example 2:
// C# Program to illustrate the // Math.Exp(Double) Method by // taking NaN, PositiveInfinity // and NegativeInfinity] using System; class Geeks { // Main Method public static void Main() { // Taking NaN Console.WriteLine(Math.Exp(Double.NaN)); // Taking PositiveInfinity Console.WriteLine(Math.Exp(Double.PositiveInfinity)); // Taking NegativeInfinity Console.WriteLine(Math.Exp(Double.NegativeInfinity)); } } |
NaN Infinity 0
