Math.exp( ) In JavaScript

The Math.exp() function in JavaScript is used to return e^x, where x is the argument, and e is Euler’s number, which is the base of the natural logarithms.
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:
Value:A number whose e^x you want to find.

Return Value:
The Math.exp() function returns e^x where e is Euler’s number and x is the argument.

Examples:

1. When zero is passed as a parameter.

   <script type="text/javascript">    document.write("Output : " + Math.exp(0)); </script>

   Output:

   Output : 1

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

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

   Output:

   Output : 0.36787944117144233 

3. When “1” is passed as a parameter.

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

   Output:

   Output :  2.718281828459045
