Parse Float with 2 Decimals in JavaScript

To parse float with 2 decimal places:

1. First, use the toFixed() method to specify the number of decimal places you want to round the number to. This method rounds the number to the nearest decimal place and Also toFixed() will return the result as a string.
2. toFixed() method rounds the number up or down, depending on the next decimal place. If you want to always round down, you can use the Math.floor() or round up you can use Math.ceil()
3. Finally, to convert the parsed number back to a number and not a string, use the parseFloat(), this will convert the string to float.

let us see parse float with 2 decimals by example.

First, assign a value that holds the floating point number which we want to parse.

let num = 6.16659265;

Then use toFixed() a method like below also mentions the number of decimal places we want to round the number for example in the below case I have mentioned 2 decimal places.

let parsedNum = num.toFixed(2);

The toFixed() method rounds the number up or down, depending on the next decimal place. If we want to always round down, we can use the Math.floor() function. if you want nearest integer please use Math.round() function see the last example.

let parsedNum = Math.floor(num * 100) / 100;

If we want to always round up, we can use the Math.ceil() function.

let parsedNum = Math.ceil(num * 100) / 100;

Finally, If we need to convert the parsed number to a string, use the parseFloat() else you can you the value from the last step directly, like the below example.

let finalNumber = parseFloat(parsedNum);

Also, we can use the Math.round() function to method returns the value of a number rounded to the nearest integer.

let parsedNum = Math.round(num * 100) / 100;
