Last Updated : 22 Jun, 2023

The predefined math functions in PHP are used to handle the mathematical operations within the integer and float types. These math functions are part of the PHP core.

Installation: These functions have not required any installation. The complete list of PHP math functions are given below:

Example: Programs illustrate the decbin() function in PHP:

PHP

<?php 
echo decbin(12); 
?>

Output:
