How can PHP's rounding behavior affect the accuracy of calculations involving complex numbers?

PHP's rounding behavior can affect the accuracy of calculations involving complex numbers because it may introduce small errors in the calculations due to rounding. To solve this issue, you can use the `bcmath` extension in PHP, which provides arbitrary precision mathematics functions for accurate calculations involving complex numbers. 

<?php

// Enable the bcmath extension
if (!extension_loaded('bcmath')) {
    die('bcmath extension is not loaded');
}

// Perform complex number calculations with arbitrary precision
$real1 = '1.23456789';
$imaginary1 = '2.34567890';
$real2 = '3.45678901';
$imaginary2 = '4.56789012';

$sum_real = bcadd($real1, $real2, 10);
$sum_imaginary = bcadd($imaginary1, $imaginary2, 10);

echo "Sum: $sum_real + $sum_imaginary i\n";

?>
