The Math object is a predefined JavaScript object used to perform mathematical operations. It’s also used to obtain the values of predefined mathematical constants, i.e., Pi (π) or the square root of a number. In addition, it can also be used to generate random numbers.
It’s important to remember that the Math object begins with an uppercase “M.” If a lower case “m” is used, the JavaScript interpreter will not recognize it as an object.
(Note: We won’t cover all of these properties and methods in detail as some of them are a little more complicated than what we are dealing with right now.)
| Name | Description |
| E | The value of Euler’s constant, approximately 2.718 |
| LN2 | The natural logarithm of 2, approximately 0.693 |
| LN10 | The natural logarithm of 10, approximately 2.302 |
| LOG2E | The base 2 logarithm of E, approximately 1.442 |
| LOG10E | The base 10 logarithm of E, approximately 0.434 |
PI (π) |
The ratio of the circumference of a circle to its diameter, approximately 3.14159 |
| SQRT1_2 | Square root of 1/2; equivalently, 1 over the square root of 2, approximately 0.707 |
| SQRT2 | Square root of 2, approximately 1.414 |
You can use this script to calculate the circumference of a circle using Pi by entering the radius:
Let’s see what we did in this script.

You would then add this in the body section of the page in order to call the script above:
Let’s take a look at the JavaScript math methods and see what we can do with them.
