We can use Ruby to find the ceiling of a number by using the **ceil** method. The **ceil** Ruby method rounds a number up to the nearest integer.

`4.653.ceil`

The above code would return 5, as it would round the number `4.653`

up to 5.

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

`4.653.ceil(2)`

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

```
num1 = 4.653.ceil
num2 = 4.653.ceil(2)
puts num1
puts num2
#Output:
5
4.66
```

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

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

Below are some examples of how to use **ceil** in Ruby to round up and find the ceiling of numbers.

```
puts 5.2.ceil
puts 10.867986.ceil(3)
puts 43.5.ceil(1)
puts -12.3.ceil
puts -0.3.ceil
#Output:
6
10.868
43.5
-12
-0.0
```

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

Hopefully this article has been beneficial for you to learn how to get the ceiling in Ruby of a number by using the Ruby ceil method.
