Frequently Asked Questions
What does the ceiling function do?
The ceiling function rounds any number up to the smallest integer that is greater than or equal to it, moving toward positive infinity.
What is the ceiling of 4.3?
The smallest integer greater than or equal to 4.3 is 5, so the ceiling of 4.3 equals 5.
What is the ceiling of a negative number, such as negative 4.3?
The ceiling still moves toward positive infinity, so the ceiling of negative 4.3 is negative 4, not negative 5.
What is the ceiling of a whole number?
If the input is already an integer, the ceiling function returns that same number unchanged.
