JavaScript: Math.E property
This JavaScript tutorial explains how to use the math property called Math.E with syntax and examples.
Description
In JavaScript, Math.E is a math property that is used to return the mathematical constant e which is the base of natural logarithms. Because Math.E is a property of the Math object, it must be invoked through the placeholder object called Math.
Syntax
In JavaScript, the syntax for the Math.E property is:
Math.E;
Parameters or Arguments
There are no parameters or arguments for the Math.E property.
Returns
The Math.E property returns the mathematical constant e which has an approximate value of 2.71828.
Note
- The Math.E property is a property of the Math object and not a math function. However, we have included the Math.E property within our JS Math Functions section because you will most likely use this property in conjunction with the Math functions found in this section.
Example
Let's take a look at an example of how to use the Math.E property in JavaScript.
For example:
console.log(Math.E);
In this example, we have invoked the Math.E property using the Math class.
We have written the output of the Math.E property to the web browser console log, for demonstration purposes, to show what the Math.E property returns.
The following will be output to the web browser console log:
2.718281828459045
In this example, the Math.E property returned a value of 2.718281828459045 which is the value of the mathematical constant e. This is the value of the base of natural logarithms.
