# Number.prototype.toFixed()

The ** toFixed()** method formats a number using fixed-point notation.

## Syntax

<var>numObj</var>.toFixed([<var>digits</var>])

### Parameters

`digits`

- Optional. The number of digits to appear after the decimal point; this may be a value between 0 and 20, inclusive, and implementations may optionally support a larger range of values. If this argument is omitted, it is treated as 0.

### Return value

A string representing the given number using fixed-point notation.

### Exceptions

`RangeError`

- If
`digits`

is too small or too large. Values between 0 and 20, inclusive, will not cause a`RangeError`

. Implementations are allowed to support larger and smaller values as well. `TypeError`

- If this method is invoked on an object that is not a
`Number`

.

## Description

** toFixed()** returns a string representation of

`numObj`

that does not use exponential notation and has exactly `digits`

digits after the decimal place. The number is rounded if necessary, and the fractional part is padded with zeros if necessary so that it has the specified length. If `numObj`

is greater than `1e+21`

, this method simply calls `Number.prototype.toString()`

and returns a string in exponential notation.## Examples

### Using `toFixed`

var numObj = 12345.6789; numObj.toFixed(); // Returns '12346': note rounding, no fractional part numObj.toFixed(1); // Returns '12345.7': note rounding numObj.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 that it rounds up in this case. -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' (...unless you use parentheses)
