Math Object in JavaScript

The Math object in JavaScript is a built-in object that provides a variety of mathematical functions and constants. It's not a constructor, so it cannot be instantiated. All properties and methods are static and can be accessed directly via the Math object.

Common Math Properties and Methods

    • Description: Returns the smallest positive number in JavaScript.

    • Example:

      console.log(Math.MIN_VALUE);  // Output: 5e-324
      
      

Math Methods

1. Math.abs(x):

   • Description: Returns the absolute (positive) value of x.

   • Example:

     console.log(Math.abs(-5));  // Output: 5
     console.log(Math.abs(5));   // Output: 5
     
     

2. Math.ceil(x):

   • Description: Returns the smallest integer greater than or equal to x.

   • Example:

     console.log(Math.ceil(4.3));  // Output: 5
     console.log(Math.ceil(9.01)); // Output: 10
