PHP Math, जैसे की नाम ही आप समझ गए होंगे, इसका इस्तेमाल किसी भी mathematical operations के लिए किया जाता है।
PHP कई पूर्वनिर्धारित गणित स्थिरांक (math constants) और functions प्रदान करता है जो की किसी भी mathematical operations करने की अनुमति देते हैं। जैसे की किस numbers की elementary exponential, logarithm, square root निकालना और भी कई function.
कुछ PHP Math के उदाहरण नीचे दिए गए हैं:max(x,y): इसका इस्तेमाल x और y में से highest वैल्यू धुंडने के लिए किया जाता है।min(x,y): इसका इस्तेमाल x और y में से lowest वैल्यू धुंडने के लिए किया जाता है।sqrt(x): इसका इस्तेमाल x का square root निकालने के लिए किया जाता है।abs(x): इसका इस्तेमाल x की positive वैल्यू को दर्शानेके लिए किया जाता है।
Example:1 PHP Math
<?php
$x = 64;
$y = 75;
echo (max($x, $y)); //Result: 75
echo "<br>";
echo (min($x, $y)); //Result: 64
echo "<br>";
echo (sqrt($y)); //Result: 8
echo "<br>";
echo (abs($x - $y)); //Result: 11
?>
Example:2 PHP Math
<?php
echo (max(54, 15, 356)); //Result: 356
echo "<br>";
echo (min(54, 15, 356)); //Result: 15
echo "<br>";
echo (sqrt(16)); //Result: 4
echo "<br>";
echo (abs(5 - 15)); //Result: 10
?>
