Rounding and Formatting Numbers

By Angela Bradley, About.com Guide

The Ceil () PHP function is used to always round up to the nearest whole number. The PHP function Ceil () behaves identical to the MySQL use; even the smallest decimal will always be rounded up.

<?php 
 echo ceil(3.14159265); 
 // Value would be 4
 echo ceil(3.00000001); 
 // Value would be 4
 echo ceil(-3.14159265); 
 // Value would be -3
 ?>
