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 −
Example
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.
Output
This will produce the following output −
PS C:\Users\Amit\JavaScript-code> node demo38.js Actual value=200.432144444555 Modified value=200.4
