  • 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.


Syntax:


Math.exp(value)


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.
