The Most Frequently Used Javascript Math Objects

Complete guides to Javascript Math Objects. Javascript has a builtin object that can be used to performing mathematical calculations. You don’t need to create some formula and functions manually to do the calculations that already have standardization.

For example, to get an absolute/positive value on a negative number, You can use Math.abs() function to return the positive number. In this Javascript tutorial, I will provide a complete reference to the most frequently used Math objects in Javascript and how to use it in the application.

What is the Javascript Math Object?

The Math object is a Javascript object that contains mathematical functions and some constants to do accurate calculations like sin, cos, tan, exponent, square root.

The Math JavaScript object is different from the JavaScript operator. Object math aims to shorten formulas and calculations rather than using Javascript operators. (I have discussed Javascript operators, please read the Javascript operator tutorial)

Here is a list of functions of the Javascript Math object that often used

List of Javascript Objects Math functions and constants

Calculation of logarithms, powers of numbers and Javascript exponentials

Math.log(x)

Used for calculating logarithmic operations.

Example:

Math.pow()

The function used to calculate the power of numbers

Example

Math.exp()

Used to calculate exponential formulas.

Example:

Trigonometric calculations

Math.acos(x)

Returns the cosine arc between the value 0 and pi in radians

Example:

Math.asin(x)

Returns the arcsine of x (x in radians)

Example:

Math.atan(x)

Used to return the arctangent of x as a numerical value between pi/2 and pi/2 radians

Example:

Math.atan2(y,x)

Javascript Math object to return the arctangent of the result for an argument

Example:

Math.cos(x)

Javascript object to return cosine of x (x in radians)

Example:

Math.sin()

Used to return a sine of x (x is radians)

Example:

Math.tan(x)

Used to return the tangent value from an angles in radians

Example:

Javascript Rounding Function

Math.round(x)

Used to round numbers to the nearest integer number:

Example:

Math.floor(x)

Used for round down integer values

Example:

Math.ceil(x)

Used for round up integer values

Example:

Javascript Root Function

Math.sqrt(x)

Javascript function to return square root of x

Example:

Math.cbrt(x)

The Javascript function to return a cubic root of x

Example:

JS function to return the absolute number

Math.abs(x)

Used to return the absolute number of x

Example:

Javascript object math function to find the highest and lowest numbers

Math.max(x,y,z,…,n)

Used to return a number with the highest value

js examples:

Math.min(x,y,z,…,n)

Used to return a number with the lowest value

Example:

Javascript random function

Math.random()

used to return random numbers between 0.0 to 1

Example:

In addition to the Math object function, Javascript also has constant math/ math property objects like pi, LN10, E

Conclusion

• Math objects are objects that are specifically used for mathematical calculations or operations.
• You will use it a lot in making programs that require mathematical calculations.

So the tutorial for learning JavaScript properties and methods in Math Objects, hopefully easy to understand.
