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:
1100
