The Ceiling Function
The ceiling function (also known as the least integer function) of a real number \(x\) is the smallest integer that is greater than or equal to \(x\).
It is denoted as \(\lceil x \rceil\).
Formula:
\( \lceil x \rceil = \min \{ n \in \mathbb{Z} \mid n \ge x \} \)
In simpler terms, it always rounds the number up to the next whole number.
Examples:
- \(\lceil 3.14 \rceil = 4\)
- \(\lceil 7 \rceil = 7\)
- \(\lceil -2.7 \rceil = -2\)
Calculates the smallest integer greater than or equal to a number.
