The JavaScript 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.

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

Example 1: 

Javascript




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


Output: 

When zero is  passed as a parameter: 1

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

Javascript




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


Output: 

Result : 0.36787944117144233 

Example 3: When “1” is passed as a parameter. 

Javascript




<script type="text/javascript">
