# JavaScript round

The JavaScript round function is a Math function used to round the specified expression or an individual number to the nearest integer. The syntax of the JavaScript code round function is

`Math.round(number);`
• If the number argument is a positive or negative number, it will return the nearest value.
• If it is not a number, the function will return NaN.
• And, if the number argument is Null, it will return Zero.

## JavaScript round Number Example

In this round function example, we will round the values of different data types and display the output.

1. First two statements, we used the JavaScript Function on the Positive and negative integers.
2. We used the positive and negative decimal values for the next four statements.
3. Next, we tried on the string value. It will return NaN as output
4. Last, We tried this Math method on Null value, and it returns Zero
