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);
