Example 1:
Ruby
# Ruby program for ceil() method in Numeric # Initialize a number num1 = -19
num2 = -18.97
num3 = 18.98
# Prints ceil() of num puts num1.ceil() puts num2.ceil() puts num3.ceil() |
Output:
-19 -18 19
Example 2:
Ruby
# Ruby program for ceil() method in Numeric # Initialize a number num1 = -19.897
num2 = -18.321
num3 = 190.23213
# Prints ceil() of num puts num1.ceil(1)
puts num2.ceil(2)
puts num3.ceil(3)
|
Output:
-19.8 -18.32 190.233
