# JavaScript .toFixed() Method with Examples

## Overview

In this javascript toFixed method tutorial, we would love to describe how to use the number method called toFixed with new examples.

### JavaScript toFixed() method

The JavaScript toFixed () method is used to round( formats ) a number to a fixed notation point or convert the number into a string and its representation of a number with a specified number of decimal points. It returns value as a string.

#### Syntax:

`number.toFixed(n);`
##### Here,
• The first thing is n is an optional parameter in toFixed function.
• The second thing is, n is a number of digits after the decimal place to display in the result.

#### List of Examples of toFixed Methods

Let’s take a look at an example javascript number format one decimal point, two decimal points or without decimal using the toFixed() method in JavaScript.

``` var number = 111.123456;

number.toFixed();
number.toFixed(1);
number.toFixed(2);

//Output
111
111.1
111.12```

#### Source code of this Example

```<!DOCTYPE html>
<html>
<title>JavaScript toFixed() Method Example</title>
<body>
<button onclick="myFunction()">Click &amp; See Result</button>

<p id="demo"></p>
<p id="demo1"></p>
<p id="demo2"></p>

<script>
function myFunction() {
var num = 5230.2256545;
var n = num.toFixed()
var n1 = num.toFixed(1)
var n2 = num.toFixed(2)
document.getElementById("demo").innerHTML = n;
document.getElementById("demo1").innerHTML = n1;
document.getElementById("demo2").innerHTML = n2;
}
</script>

</body>
</html>
```

Assuming you have a decimal number greater than the real number, taps are added to make the desired decimal length.

#### Javascript toFixed With and Without Rounding

Let’s take a new example for rounding a number with or without using .toFixed function.

```<!DOCTYPE html>
<html>
<title>Javascript tofixed With and Wthout Rounding Example</title>
<body>
<button onclick="calFucntion()">Click &amp; See Result</button>
<br><br>
<b>With Round :-</b> <p id="withRound"></p>
<b>Without Round :-</b> <p id="roundValue"></p>

<script>
function calFucntion() {
var num = 5285.8556545;
var withRound = num.toFixed(2);
var with2Decimals = num.toString().match(/^-?\d+(?:\.\d{0,2})?/)[0];
document.getElementById("withRound").innerHTML = withRound;
document.getElementById("roundValue").innerHTML = with2Decimals;
}
</script>

</body>
</html>
```

#### Demo

Javascript tofixed With and Wthout Rounding Example

With Round :-

Without Round :-

#### Let’s see the Examples

```var num = 12345.6789;

num.toFixed();       // Returns '12346': note rounding, no fractional part
num.toFixed(1);      // Returns '12345.7': note rounding
num.toFixed(6);      // Returns '12345.678900': note added zeros
(1.23e+20).toFixed(2);  // Returns '123000000000000000000.00'
(1.23e-10).toFixed(2);  // Returns '0.00'
2.34.toFixed(1);        // Returns '2.3'
2.35.toFixed(1);        // Returns '2.4'. Note it rounds up
2.55.toFixed(1);        // Returns '2.5'. Note it rounds down - see warning above
-2.34.toFixed(1);       // Returns -2.3 (due to operator precedence, negative number literals don't return a string...)
(-2.34).toFixed(1);     // Returns '-2.3'
```
