//There are meny ways of rounding...
Math.floor(5.5) //Answer 5, it alwas rounds down.
Math.round(5.5) //Answer 6, it simpily rounds to the closest whole number.
Math.ceil(5.5) //Answer 6, it alwas rounds up.
//You can do more things too...
Math.floor(5.57 * 10) / 10 //Answer 5.5, the number turns into 55.7, Then gets floored (55.0), Then gets divied, (5.5).

// Example using the round function
let num = 3.14159;
let roundedNum = Math.round(num);
console.log(roundedNum); // Output: 3
