# JavaScript - The Math Object

The math object provides you properties and methods for mathematical constants and functions. Unlike other global objects, Math is not a constructor. All the properties and methods of Math are static and can be called by using Math as an object without creating it.
Thus, you refer to the constant pi as Math.PI and you call the sine function as Math.sin(x), where x is the method's argument.

### Syntax

The syntax to call the properties and methods of Math are as follows
```var pi_val = Math.PI;
var sine_val = Math.sin(30);```

## Math Properties

Here is a list of all the properties of Math and their description.
Sr.NoProperty & Description
1E \
Euler's constant and the base of natural logarithms, approximately 2.718.
2LN2
Natural logarithm of 2, approximately 0.693.
3LN10
Natural logarithm of 10, approximately 2.302.
4LOG2E
Base 2 logarithm of E, approximately 1.442.
5LOG10E
Base 10 logarithm of E, approximately 0.434.
6PI
Ratio of the circumference of a circle to its diameter, approximately 3.14159.
7SQRT1_2
Square root of 1/2; equivalently, 1 over the square root of 2, approximately 0.707.
8SQRT2
Square root of 2, approximately 1.414.
In the following sections, we will have a few examples to demonstrate the usage of Math properties.
