Javascript Math

In JavaScript, Math is a built-in object. It has both properties and methods for mathematical functions and constants.

Math operates with the Number type, but never with BigInt.

Unlike other global objects, Math is not considered a constructor. The methods and properties of Math are fixed. You can call them by applying Math as an object without creating it.

So, you refer to constant pi as Math.PI. Hence, the sine function should be called Math.sin(x). Here, x is the argument of the method.

The syntax to call the methods and properties of Math is the following:

var pi_value = Math.PI;
var sin_value = Math.sin(30);
