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

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
