2 3 In Decimal Point

While developing a web application, programmers frequently need to manipulate the information stored in the database and transform floating-point and double-precision numbers into integer numbers. Are y'all stuck in a like situation? If yep, and then no need to worry! JavaScript predefined methods can aid you.

This blog will demonstrate the methods for removing digits after the decimal points in JavaScript.

How to Remove Digits After Decimal in JavaScript?

To eliminate or remove digits afterwards decimal in JavaScript, you can use:

parseInt() method
Math.trunc() method
Math.round() method
Math.flooring() method
Math.ceil() method

Let'southward bank check how these methods perform!!

Method ane: Remove Digits After Decimal Using parseInt() Method

Using the JavaScript predefined "parseInt()" method, the specified number is parsed to the nearest whole number.

Syntax
Apply the beneath syntax for the parseInt() method:

Hither, "number" is passed to the parseInt() method that will parse information technology and remove the digits from the decimal bespeak.

Check out the following case!

Case
In this example, we volition pass the number "17.90" to the "parseInt()" method for eliminating the digits after the decimal betoken:

panel.log (parseInt( 17.xc ) ) ;

Here, the output shows that the parseInt() method successfully removed the digits "90" from the number "17.90":

Allow's move to the second method!

Method 2: Remove Digits After Decimal Using Math.trunc() Method

The most common method for removing decimal places in JavaScript is "Math.trunc()". It accepts the input in the form of positive, negative, or floating-signal numbers and outputs the integer part after removing the digits after the decimal point.

Syntax
Follow the given syntax for removing digits afterwards decimal using the trunc() method:

Example
In this example, we will pass the number "128.45" to the "Math.trunc()" method:

console.log ( Math.trunc ( 128.45 ) ) ;

The digits "45" are at present removed from the specified number:

Let'due south see another method.

Method 3: Remove Digits After Decimal Using Math.round() Method

The "Math.round()" method rounds off the decimal value to the nearest integer.

Syntax
The round() method can exist used with the syntax shown beneath:

Example
Hither, we will pass the number "65.72" to the round() method to remove the decimal part of the number, which is "72":

"66" is returned as output considering of the digit "7" after the decimal point, the Math.round() method incremented or round off the given number:

Method 4: Remove Digits Afterward Decimal Using Math.floor() Method

The "Math.floor()" method e'er rounds downwardly the number to the nearest integer nearest zero.

Syntax
Follow the below-provided syntax to use the Math.floor() method for eliminating digits afterwards the decimal point:

Instance
We will pass the number "2.96" equally a parameter in the Math.floor() method to eliminate the decimal part of it:

Output

Method 5: Remove Digits Afterward Decimal Using Math.ceil() Method

The "Math.ceil()" method of the Math class returns the adjacent largest integer of the input float number. It works the contrary of the Math.flooring() method.

Syntax
Follow the below-given syntax to use the Math.ceil() method:

Example
Here, we will pass the number "14.7" to the Math.ceil() method:

It tin can exist seen from the output that the number "xiv.7" is rounded to "xv":

Nosotros have compiled all the methods for eliminating digits later on the decimal points in JavaScript.

Conclusion

For removing digits later on decimal point, you lot tin can use the JavaScript built-in methods including parseInt(), Math.trunc(), Math.round(), Math.floor(), or Math.ceil(). All of these methods efficiently remove the digits after the decimal point. The Math.trunc() method is the most normally used method for this purpose. In this weblog, nosotros accept demonstrated the methods for eliminating or removing digits afterward the decimal points in JavaScript with detailed examples.
