//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).

The Math.round() function
returns the value of a number rounded to the nearest integer.
Math.round(x)
// If x = 0.6 it gives you 1; if x = 2.5 it gives you 3;
// if x=2.49999 it gives you 2.
Math.round( 20.49); // 20
Math.round( 20.5 ); // 21
Math.round( 42 ); // 42
Math.round(-20.5 ); // -20
Math.round(-20.51); // -21

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

// Round a number
var number = 4.7;
var roundedNumber = Math.round(number);

// The Math.round() method rounds a number to the nearest integer.
// 2.49 will be rounded down (2), and 2.5 will be rounded up (3).
// EXAMPLE: 1
let floating_num = Math.round(2.65);
console.log(floating_num);
// OUTPUT: 3
// EXAMPLE: 2
let floating_num_2 = Math.round(2.45);
console.log(floating_num_2);
// OUTPUT: 2
// EXAMPLE: 3
let floating_num_3 = Math.round(7.50);
console.log(floating_num_3);
// OUTPUT: 8
// EXAMPLE: 4
let floating_num_4 = Math.round(-2.65);
console.log(floating_num_4);
// OUTPUT: -3
// EXAMPLE: 5
let floating_num_5 = Math.round(-2.45);
console.log(floating_num_5);
// OUTPUT: -2
