PHP Math Functions

PHP has a set of math functions that allows you to perform mathematical tasks on numbers. Some of the most commonly used math functions are:

abs(): Returns the absolute value of a number.

ceil(): Rounds a number up to the nearest integer.

floor(): Rounds a number down to the nearest integer.

max(): Returns the highest value in a list of numbers.

min(): Returns the lowest value in a list of numbers.

round(): Rounds a number to a specified number of decimal places.

sqrt(): Returns the square root of a number.

pow(): Returns the power of a number.

log(): Returns the logarithm of a number.

sin(): Returns the sine of a number.

cos(): Returns the cosine of a number.

tan(): Returns the tangent of a number.

You can use these functions in your PHP code to perform a variety of mathematical tasks. For example, you could use the abs() function to calculate the absolute value of a number, or the ceil() function to round a number up to the nearest integer.

Here are some examples of how to use math functions in PHP:

// Calculate the absolute value of -5

$abs = abs(-5);

// Round 3.1415926535898 to 2 decimal places

$rounded = round(3.1415926535898, 2);

// Find the highest value in the array [1, 2, 3, 4, 5]

$highest = max([1, 2, 3, 4, 5]);

// Find the lowest value in the array [1, 2, 3, 4, 5]

$lowest = min([1, 2, 3, 4, 5]);
