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

  • Example:
    filter_none

    edit
    close

    play_arrow

    link
    brightness_4
    code

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

    chevron_right

    
    

  • 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.
