JavascriptWeb DevelopmentObject Oriented Programming

To round the decimal number to the nearest tenth, use toFixed(1) in JavaScript. The syntax is as follows −

var anyVaribleName=yourVariableName.toFixed(1)

Let’s say the following is our decimal number −

var decimalValue =200.432144444555;
console.log("Actual value="+decimalValue)

Let’s now round the decimal number. Following is the code −


var decimalValue =200.432144444555;
console.log("Actual value="+decimalValue)
var modifiedValue=decimalValue.toFixed(1)
console.log("Modified value="+ modifiedValue);

To run the above program, you need to use the following command −

node fileName.js.

Here, my file name is demo38.js.


This will produce the following output −

PS C:\Users\Amit\JavaScript-code> node demo38.js
Actual value=200.432144444555
Modified value=200.4
