# JavaScript Math round() Method

Last Updated : 20 Dec, 2023

Javascript Math.round() method is used to round a number to its nearest integer. If the fractional part of the number is greater than or equal to .5, the argument is rounded to the next higher integer. If the fractional part of the number is less than .5, the argument is rounded to the next lower integer.

### Syntax:

`Math.round(value);`

#### Parameters:

• value: It is the number that you want to round off.

#### Return Value:

The Math.round() method returns the value of the given number rounded to the nearest integer.

Example 1: To round off a number to its nearest integer.

## javascript

 `let round =Math.round(-5.8);` `console.log(``"Number after rounding : "` `+ round);`

Output

```Number after rounding : -6
```

Example 2: The Math.round() method itself rounds off a negative number when passed as a parameter to it. To round off a negative number to its nearest integer, the Math.round() method should be implemented in the following way:

## javascript

 `let round =Math.round(-5.8);` `console.log(``"Number after rounding : "` `+ round);`

Output

```Number after rounding : -6
```

Example 3: The below program shows the result of the Math.round() method when the parameter has “.5” in decimal.

## javascript

 `let round =Math.round(-12.5);` `console.log(``"Number after rounding : "` `+ round);` `let round1 =Math.round(12.51);` `console.log(``"Number after rounding : "` `+ round1);`
