Math JS

In JavaScript, Math is a built-in object that gives you common math constants

And functions like rounding, square root, power, and random numbers.

It is not a normal object you create with new;

you use it directly like Math.PI or Math.sqrt(25)

Simple idea

• Math.PI gives the value of pi

• Math.round(4.6) gives 5

• Math.floor(4.9) gives 4

• Math.ceil(4.1) gives 5

• Math.sqrt(25) gives 5

• Math.pow(2, 3) gives 8

• Math.random() gives a random decimal between 0 and 1
