How to use math functions in PHP
PHP comes with various math functions that can be used to perform common arithmetic operations. These functions make it easier to perform complex mathematical calculations in PHP. Here are some of the commonly used math functions in PHP:
Syntax:
The syntax for using a PHP math function is:
function_name(parameter); e.g. round(4.3);
Parameter Values:
| Parameter | Description |
|---|---|
| number | The number to perform the mathematical operation on |
| precision | Optional parameter for setting the precision for functions like round() and ceil() |
| base | Optional parameter for setting the base for functions like bindec() and decoct() |
Technical Details:
| Function | Description |
|---|---|
| abs() | Returns the absolute value of a number |
| sqrt() | Returns the square root of a number |
| round() | Rounds a number to the nearest integer |
| ceil() | Rounds a number up to the nearest integer |
| floor() | Rounds a number down to the nearest integer |
| max() | Returns the highest value from a set of numbers |
| min() | Returns the lowest value from a set of numbers |
| rand() | Returns a random number |
Here are some usage examples:
// absolute value echo abs(-4.2); // outputs 4.2 // square root echo sqrt(16); // outputs 4 // round to nearest integer echo round(4.3); // outputs 4 // round up to nearest integer echo ceil(4.1); // outputs 5 // round down to nearest integer echo floor(4.9); // outputs 4 // find highest value echo max(1, 3, 4, 2); // outputs 4 // find lowest value echo min(1, 3, 4, 2); // outputs 1 // generate a random number between 1 and 100 echo rand(1, 100);
