ceil

Line room's top

Ceil is a mathematical function that rounds a number up to the nearest integer, regardless of how close the number is to the integer below.

So 4.1 and 4.9 both ceil to 5.

Short for ceiling, it's the counterpart to floor, which rounds down.

Common in programming: Math.ceil(3.2) returns 4.
