PHP math functions

PHP supports and comes with many inbuilt math functions, which always comes handy while performing complex calculation rather than writing your own logic for doing mathematical operations, which can be time-consuming.

We have summarized all important math functions at one place with examples.

So let’s take a look.

Some examples

<?php

echo "<h3>PHP Math Functions</h3>";

echo "rand() = " . rand() . "<br>"; // any random number

echo "pi() = " . pi() . "<br>"; // 3.1415926535898

echo "round(3.141592653,2) = " . round(3.141592653,2) . "<br>"; // 3.14

echo "pow(3,4) = " . pow(3,4) . "<br>"; // 81

echo "sqrt(25) = " . sqrt(25) . "<br>"; // 5

echo "max(2,6) = " . max(2,6) . "<br>"; // 6

echo "log(10) = " . log(10) . "<br>"; // 2.302585092994

echo "log10(10) = " . log10(10) . "<br>"; // 1

echo "deg2rad(60) = " . deg2rad(60) . "<br>"; // 1.0471975511966

echo "rad2deg(0.78539816339745) = " . rad2deg(0.78539816339745) . "<br>"; // 45

echo "sin(30) = " . sin(deg2rad(30)) . "<br>"; // 0.5

echo "exp(0) = " . exp(0) . "<br>"; // 1

echo "abs(0.10500) = " . abs(0.10500) . "<br>"; // 0.105

echo "hypot(3,4) = " . hypot(3,4) . "<br>"; // 5

echo "decbin(5) = " . decbin(5) . "<br>"; // 101

echo "bindec(101) = " . bindec(101) . "<br>"; // 5

echo "decoct(12) = " . decoct(12) . "<br>"; // 14

echo "octdec(14) = " . octdec(14) . "<br>"; // 12

echo "dechex(15) = " . dechex(15) . "<br>"; // f

?>
