Usage

To use the rounding function, import it into your JavaScript file:

javascript const roundNearestEven = require('math-base-special-round-nearest-even');

Now you can use the function to round numbers as needed.

API

roundNearestEven(value)

• Parameters:

  • value (number): The number to round.

• Returns:

  • (number): The rounded integer.

Example

```javascript const roundNearestEven = require('math-base-special-round-nearest-even');

console.log(roundNearestEven(2.5)); // Output: 2 console.log(roundNearestEven(3.5)); // Output: 4 console.log(roundNearestEven(1.5)); // Output: 2 console.log(roundNearestEven(4.5)); // Output: 4 ```

Examples

Rounding Positive Numbers

javascript console.log(roundNearestEven(3.2)); // Output: 3 console.log(roundNearestEven(4.7)); // Output: 5

Rounding Negative Numbers

javascript console.log(roundNearestEven(-3.2)); // Output: -3 console.log(roundNearestEven(-4.7)); // Output: -5

Handling Edge Cases

javascript console.log(roundNearestEven(0.5)); // Output: 0 console.log(roundNearestEven(-0.5)); // Output: 0
