## How to Write Answer in JavaScript to a Fixed Decimal Number

If you want to write an answer in JavaScript to a fixed decimal number, there are a few ways to do it. One way is to use the `toFixed()`

method. This method will return a string that represents the number with the specified number of decimal places.

### Syntax

`number.toFixed(digits)`

Where:

`number`

: The number you want to format.`digits`

: The number of digits after the decimal point. This is an optional parameter. If omitted, it defaults to 0.

Here's an example:

```
const num = 123.456789;
const formattedNum = num.toFixed(2);
console.log(formattedNum); // Output: "123.46"
```

In this example, we have a number `123.456789`

. We call the `toFixed()`

method with `2`

as the argument, which means we want to format the number with two decimal places. The method returns a string `"123.46"`

, which we assign to the `formattedNum`

variable.

Another way to format a number to a fixed decimal point is by using the `Number()`

constructor, which will convert the string to a number with the specified number of decimal places. Here's how you can use it:

```
const num = 123.456789;
const formattedNum = Number(num.toFixed(2));
console.log(formattedNum); // Output: 123.46
```

In this example, we use the same number `123.456789`

, but instead of returning a string, we convert it back to a number using the `Number()`

constructor. The `toFixed()`

method is used to format the number to two decimal places, and then the resulting string is converted back to a number using `Number()`

.

Both methods work the same way, so use whichever one you're more comfortable with.
