flip the order of round_up and round_down.

When using ceiling() and floor() on the numeric value 3.14, why does the ceiling() function round up the value to 4?

I tried printing both values in one line by writing the following:

print (round_down, round_up)

Only got the first value printed. When I printed the values separately, both worked fine. What is the problem with printing multiple values at once?

Hello, @dzham. Welcome to the forum.

Every language has it’s nuances. There are several ways to do what you suggest, but from what I can tell, using `paste()` seems to be the easiest for what you’ve attempted.
For example:

``````print(paste("Value One:", variable_one, "Value Two:", variable_two))
``````

I’ve only dabbled in R a little bit so far myself, so you may find a better answer elsewhere. Happy coding!

ndag,

Just as the ceiling is at the top of a room (4) and the floor is at the bottom (3) for something in the middle (3.14), the functions round accordingly to the whole number above or below.

data ← c(120,22,22,31,15,120)

unique(data); #Outputs (120,22,31,15)

unique_vals = unique(data)

print(unique_vals)

solution ← sqrt(49)

print(solution)

round_down ← floor(3.14)

round_up ← ceiling(3.14)

print(round_up)

print(round_down)

is the right answer.
