JavaScript Math Object

JavaScript Math object is used to perform mathematical operations on numbers. All the properties of Math are static and unlike other objects, it does not have a constructor.

We use Math only on Number data type and not on BigInt

Example 1: This example uses math object properties to return their values. 

console.log("Math.LN10: " + Math.LN10);
console.log("Math.LOG2E: " + Math.LOG2E);
console.log("Math.Log10E: " + Math.LOG10E);
console.log("Math.SQRT2: " + Math.SQRT2);
console.log("Math.SQRT1_2: " + Math.SQRT1_2);
console.log("Math.LN2: " + Math.LN2);
console.log("Math.E: " + Math.E);
console.log("Math.PI: " + Math.PI);

Math.LN10: 2.302585092994046
Math.LOG2E: 1.4426950408889634
Math.Log10E: 0.4342944819032518
Math.SQRT2: 1.4142135623730951
Math.SQRT1_2: 0.7071067811865476
Math.LN2: 0.6931471805599453
Math.E: 2.71828...

Example 2: Math object methods are used in this example. 

console.log("Math.abs(-4.7): " + Math.abs(-4.7)); 
console.log("Math.ceil(4.4): " + Math.ceil(4.4)); 
console.log("Math.floor(4.7): " + Math.floor(4.7)); 
console.log("Math.sin(90 * Math.PI / 180): " +
        Math.sin(90 * Math.PI / 180)); 
console.log("Math.min(0, 150, 30, 20, -8, -200): " +
        Math.min(0, 150, 30, 20, -8, -200)); 
console.log("Math.random(): " + Math.random()); 

Math.abs(-4.7): 4.7
Math.ceil(4.4): 5
Math.floor(4.7): 4
Math.sin(90 * Math.PI / 180): 1
Math.min(0, 150, 30, 20, -8, -200): -200
Math.random(): 0.7416861489868538

JavaScript Math Object – FAQs

What is the Math object in JavaScript?

The Math object is a built-in object that provides properties and methods for mathematical constants and functions. It is not a constructor, so all its properties and methods are static and can be called without creating a Math object instance.

How do you use the Math object?

You use the Math object by calling its properties and methods directly. For example, Math.PI for the value of π or Math.sqrt() for calculating the square root.

How do you generate random numbers using the Math object?

You can generate random numbers using Math.random(), which returns a floating-point number between 0 (inclusive) and 1 (exclusive). To generate a random number within a specific range, you can scale and shift the result.

How do you find the maximum or minimum of a set of numbers?

You can find the maximum or minimum of a set of numbers using Math.max() and Math.min() respectively. Both methods accept zero or more arguments.
