Introduction to JavaScript Math Functions
The JavaScript Math is a builtin object that provides properties and methods for mathematical constants and functions to execute mathematical operations. It is not a function object, not a constructor. You can call the Math as an object without creating it because the properties and methods of Math are static.
JavaScript Math Functions
The Math Functions consist of methods and properties. Following is the list of methods used with the Math object:
1)Math.round()
This method provides the value of the given Number to a rounded integer. It can be written as:
Math.round(x), where x is a number.
2)Math.pow()
It provides the value of x to the power of y. It can be written as:
Math.pow(x, y), where x is a base number and y is an exponent to the given base.
3)Math.sqrt()
It gives the square root of a given integer. It can be written as:
Math.sqrt(x), where x is a number.
4)Math.abs()
It provides the absolute i.e. positive value of a number. It can be written as:
Math.abs(x); where x is a number.
5)Math.ceil()
It gives a smaller number, which is greater or equal to the given integer. It can be written as:
Math.ceil(x); where x is a number
6)Math.floor()
It gives a larger number, which is lesser or equal to the given integer. It can be written as:
Math.floor(x); where x is a number.
7)Math.sin()
It provides a sine of the given number. It can be written as:
Math.sin(x); where x is a number.
8)Math.cos()
It provides cosine of the given number. It can be written as:
Math.cos(x); where x is a number
9)Math.min() and Math.max()
The min() method is used to display the lowest value of the given arguments. It can be written as:
Math.min(val1, val2………valn); where val1, val2………valn are numbers.
The max() method is used to display the highest value of the given arguments. It can be written as:
Math.max(val1, val2………valn); where val1, val2………valn are numbers.
10)Math.random()
It provides a random number between 0 and 1. It can be written as:
Math.random();
11)Math.acos()
It provides an arccosine of an integer. It can be written as:
Math.acos(x); where x is a number.
12)Math.asin()
It provides arcsine of an integer. It can be written as:
Math.asin(x); where x is a number.

Conclusion
As we discussed, you cannot consider the Math object as the constructor. It provides builtin properties and methods for performing mathematical tasks on numbers. To make use of the Math object, extend the Math object directly instead of using the prototype.
