Math. round() method.
number.toFixed() method preserves the user-specified decimal places when converting a number to a string type. The method will automatically add null values to produce the desired decimal length if the desired number of decimals is greater than the number that was passed.
- x is the desired number of decimal places.
This is the most suitable method to do this. All you need to do is using it with a variable that contains decimal input, like the example below.
var number = 2.38473783; // Use toFixed() method to round the number to 2 decimal places var roundedNumber = number.toFixed(2); console.log(roundedNumber);
With a parameter of two, you can get a number rounded to two decimal places. Let’s look at the output and see what it returns. That’s how this function works. Or you can also refer to the following method here.
Math. round() method has a rounding function. The method will return the nearest integer to the number provided when calling the method. If a non-numeric value is provided, the method will return NaN.
- Number: is the number to be rounded.
This way, we will round the number with the
Math. round() function. First, we multiply the number by 100 to get the number with two decimal places and divide the decimal part by dividing the number by the “/” sign. Let’s see the following code to see how we code and how this method works with decimals.
var number = 2.38473783; // Round the number and divide by the decimal var roundedNumber = Math.round(number * 100) / 100; console.log(roundedNumber);
When you use the
Map. round() method, the number returned will lose the decimal part. You should pay attention to this. The return results of the two methods are the same. I wish you success with the methods mentioned in the article
number.toFixed() method because it is built in to do this. Wish you a good day!
