Below is the example of the Math exp() Method. 

  • Example: 


<script type="text/javascript">
   document.write("When zero is  passed as a parameter: "
         + Math.exp(0));

  • Output: 
When zero is  passed as a parameter: 1

The Math.exp() method is used to return ex, where x is the argument, and e is Euler’s number, which is the base of the natural logarithms. The exp() is a static method of Math, therefore, it is always used as Math.exp(), rather than as a method of a Math object created.


Parameters Used: This function accepts a single parameter as mentioned above and described below:  

  • value is a number whose ex you want to find.

Returns: The Math.exp() method returns ex where e is Euler’s number and x is the argument.
More codes for the above method are as follows: 
Program 1: When “-1” is passed as a parameter.


<script type="text/javascript">
         document.write("Result : " + Math.exp(-1));


Result : 0.36787944117144233 

Program 2: When “1” is passed as a parameter. 


<script type="text/javascript">
         document.write("Result : " + Math.exp(1));


Result :  2.718281828459045
