PHP Math Functions

Syntax

PHP provides a set of built-in math functions that can be used to perform various mathematical operations. The syntax for using these functions is:

functionName(argument1, argument2, ...)

Example

Here is an example that demonstrates the use of some of the math functions:

$x = 4;
$y = -5;

echo abs($y); // output: 5
echo pow($x, 2); // output: 16
echo sqrt($x); // output: 2
echo max($x, $y); // output: 4
echo min($x, $y); // output: -5

Output

When running the above code, you should see the output as described in the comments.

Explanation

• abs() returns the absolute value of a number.
• pow() returns the result of raising a number to a power.
• sqrt() returns the square root of a number.
• max() returns the highest value of one or more numbers.
• min() returns the lowest value of one or more numbers.

Use

These math functions can be used in a wide range of applications, including scientific computing, financial analysis, and statistical analysis.

Important Points
