PHP Math Functions

PHP provides several math functions, including:

  • abs(): Returns the absolute value of a number.
  • ceil(): Returns the smallest integer greater than or equal to a number.
  • floor(): Returns the largest integer less than or equal to a number.
  • round(): Rounds a number to the nearest integer.
  • sin(): Returns the sine of a number.
  • cos(): Returns the cosine of a number.
  • tan(): Returns the tangent of a number.

Example of PHP Math Functions

<?php
$number = 10.5;

echo abs($number) . "\n";
// Outputs: 10.5
echo ceil($number) . "\n";
// Outputs: 11
echo floor($number) . "\n";
// Outputs: 10
echo round($number) . "\n";
// Outputs: 11
?>

Output:

10.5
11
10
11

Explanation: This example demonstrates the use of several PHP math functions, including abs(), ceil(), floor(), and round().

Single Line Example

<?php  
 echo abs(10.5) . "\n";
 echo ceil(10.5) . "\n";
 echo floor(10.5) . "\n";
 echo round(10.5) . "\n";
 echo sin(10.5) . "\n";
 echo cos(10.5) . "\n";
 echo tan(10.5) . "\n";
?>

Output:

10.5
11
