Answer 13

the book says that floor is the largest integer smaller than or equal to x, and ceiling is the smallest integer greater than or equal to x

Answer 14

floor(n) returns the largest integer smaller than or equal to n, so by example
floor(2.3) == 2
floor(2.8) == 2
floor(2.0) == 2
floor(3.01) == 3, etc.

ceil(n) is similar, it returns the smallest integer that is greater than or equal to n.
ceil(2.1) == 3
ciel(2.8) == 3
ciel(3.0) == 3
ciel(3.00001) == 4
