Ruby Ceiling – Find the Ceiling of a Number with the ceil Method

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
