Math

Math is a built-in object that has properties and methods for mathematical constants and functions. It’s not a function object.

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

Description

Unlike many other global objects, Math is not a constructor. All properties and methods of Math are static. 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. Constants are defined with the full precision of real numbers in JavaScript.

Note that trigonometric functions (sin(), cos(), tan(), asin(), acos(), atan(), atan2()) expect (and return) angles in radians.

To convert radians to degrees, divide by (Math.PI / 180). Multiply by the same value to convert degrees to radians.

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!
