// ceil is short for ceiling(up), floor is down...

define math.floor() method in javascript

// The floor() method rounds the specified double value downward to the nearest integer and returns it. 
// The rounded value will be equal to the mathematical integer. 
// That is, the value 3.24 will be rounded to 3.0 which is equal to integer 3.
// We can only use float numbers in floor().

// EXAMPLE: 1
let floating_num = Math.floor(2.65);
console.log(floating_num);
// OUTPUT: 2

// EXAMPLE: 2
let floating_num_2 = Math.floor(-2.65);
console.log(floating_num_2);
// OUTPUT: -3

// EXAMPLE: 3
let floating_num_3 = Math.floor(5);
console.log(floating_num_3);
// OUTPUT: 5
