How can PHP developers optimize their code to improve precision and accuracy in mathematical calculations for visual elements?

To optimize code for precision and accuracy in mathematical calculations for visual elements in PHP, developers can use the bcmath extension to perform arbitrary precision mathematics. This extension allows for calculations with arbitrary precision numbers, ensuring accurate results even with large or decimal numbers.

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

// Perform mathematical calculations with arbitrary precision
$bcmath_result = bcmul('1.23456789', '9.87654321', 10);

// Output the result
echo $bcmath_result;
