We have often used the ceiling function in mathematical problems to round up a decimal number to next greater integral value. PHP provides us with a built-in function ceil() to perform such operation. The ceil() function is a built-in function in PHP and is used to round a number to the nearest greater integer.
Syntax:
float ceil(value)
Parameters: The ceil() function accepts a single parameter value which represents the number which you want to round up to the nearest greater integer.
Return Value: The return type of the ceil() function is float as shown in the syntax. It returns the number which represents the value rounded up to the next highest integer.
Examples:
Input : ceil(0.70)
Output : 1
Input : ceil(-4.1)
Output : -4
Input : ceil(6)
Output : 6
Below programs illustrate the ceil() function in PHP:
- When a positive number with decimal places is passed as a parameter:
PHP
<?php
echo ( ceil (0.70));
?>
|
Output:
1
- When a negative number with decimal places is passed as a parameter:
PHP
<?php
echo ( ceil (-4.1));
?>
|
Output:
-4
- When a number with no decimal places is passed as a parameter:
Output:
6
