The ceil() function returns the rounded-up value of the input number. It always returns a float, even if the input number itself is an integer. The returned value is the smallest integer greater than or equal to the input number. For example, ceil(4.3) will return 5.
PHP Version
Since its introduction in PHP 4.2.0, the ceil() function has been included as a standard part of the PHP language. It is compatible with all PHP versions, including PHP 5, PHP 7, and PHP`` 8.
PHP Changelog
Starting from PHP 4.2.0, the ceil() function has been accessible in all subsequent versions. No significant modifications or updates have been made to the ceil() function since its initial release.
Examples of ceil() in PHP
Here are some examples that show the application of the ceil() function in PHP
Example 1:
Output:
Explanation:
In this example, the value 2.34 is supplied to the ceil method. The ceil method converts it to the smallest integer greater than or equal to 2.34, which is 3 in this case. The result is displayed finally using the echo command.
