hypot():hypotenuse of a right-angle triangle

<?Php
echo hypot(4,3); // Output is 5
echo "<br>";
echo hypot(2,3); // Output 3.605551275464
echo "<br>";
echo hypot(4,5); // Output 6.4031242374328
echo "<br>";
echo hypot(8,10); // Output is 12.806248474866
echo "<br>";
echo hypot(12,13); // Output is 17.691806012954
?>

float hypot ( float $x , float $y )

echo round(hypot(9,10),2); // Output is 13.45

Example: Calculating Hypotenuse of a Right Triangle

$a = 3;
$b = 4;
echo hypot($a, $b);  // Output: 5 (Pythagorean theorem: sqrt(3^2 + 4^2))

Example: Using Negative Values

$a = -3;
$b = 4;
echo hypot($a, $b);  // Output: 5 (Negative values are squared, so the result is positive)
