Exercise 1 - Formatting Numbers

You can format the numbers in JavaScript by using the various built-in methods such as toFixed() and toPrecision().

The toFixed() method helps to display the number with the required number of decimal values. This method returns a string value. The toFixed() method takes a single parameter. You can also use this method without any parameter.

The toPrecision() method helps to display the number with the required length or precision. This method also returns a string value. The toPrecision() method takes a single parameter that is optional.
