Built-In Mathematical Calculations

Math is a built-in object with properties and methods for mathematical constants and functions. It is not a function object. Math works with the Number type. Math functions are all static, so each starts with Math.myfunctioncallhere(). Math.PI and Math.random() are two Math functions used a lot when doing calculations.

Description

Math

The Math namespace object contains static properties and methods for mathematical constants and functions.

Math works with the Number type. It doesn't work with BigInt.


Description

Unlike most global objects, Math is not a constructor. You cannot use it with the new operator or invoke the Atomics object as a function. All properties and methods of Math are static.

Note: Many Math functions have a precision that's implementation-dependent.

This means that different browsers can give a different result. Even the same JavaScript engine on a different OS or architecture can give different results!
