The ceil Function
The ceil function rounds a fraction up to the
nearest integer. This means that regardless
of the digit at the beginning of the fractional part, the fraction will
still be rounded up by increasing the integer part
by 1. For example, 12.1 will be rounded
to 13.
Syntax
ceil(number);
Example
Let's round 5.1 up:
<?php
echo ceil(5.1);
?>
Code execution result:
6
