We can use Ruby to find the floor of a number by using the **floor** method. The **floor** Ruby method rounds a number down to the nearest integer.

`4.653.floor`

The above code would return 4, as it would round the number `4.653`

down to 4.

Note that we can also pass the floor method an integer parameter that will be the number of decimal places that we want to round the number to.

`4.653.floor(2)`

Let’s see the output of both of these simple examples.

```
num1 = 4.653.floor
num2 = 4.653.floor(2)
puts num1
puts num2
#Output:
4
4.65
```

One calculation that is very easy to perform in Ruby is finding the floor of a number.

We can find the floor of a number easily with the Ruby **floor** method.

Below are some examples of how to use **floor** in Ruby to round down and find the floor of numbers.

```
puts 5.2.floor
puts 10.867986.floor(3)
puts 43.5.floor(1)
puts -12.3.floor
puts -0.3.floor
#Output:
5
10.867
43.5
-13
-1
```

If you want to round up and get the ceiling of a number in Ruby, you can use the ceil method. To round to the nearest integer in Ruby, we can use the round method.
