In Ruby, you can use the ceil
method to round a float or decimal number up to the nearest integer, also known as the ceiling.
Here's an example:
main.rb60 chars4 lines
In this example, we first declare a variable num
and assign it the value of 3.14159. We then call the ceil
method on num
to round it up to the nearest integer, which is 4. Finally, we use the puts
method to print the value of ceil_num
to the console.
Note: The ceil
method returns a float value so if you want to get an integer value after taking the ceiling, you should use the ceil.to_i
expression instead.
