What are the potential pitfalls of complex mathematical calculations in PHP scripts?

Complex mathematical calculations in PHP scripts can lead to potential pitfalls such as decreased performance due to high computational load, increased memory usage, and potential errors in the calculations. To mitigate these issues, it is recommended to optimize the code by breaking down complex calculations into smaller, more manageable steps, using built-in PHP functions for mathematical operations, and caching results if necessary. 

// Example of optimizing complex mathematical calculations in PHP

// Break down complex calculation into smaller steps
$step1 = $number1 * $number2;
$step2 = $step1 + $number3;
$result = $step2 / $number4;

// Use built-in PHP functions for mathematical operations
$result = pow($number1, 2) + sqrt($number2);

// Cache results if necessary
$cacheKey = 'calculation_' . $number1 . '_' . $number2;
if (!apcu_exists($cacheKey)) {
    $result = $number1 * $number2;
    apcu_add($cacheKey, $result);
} else {
    $result = apcu_fetch($cacheKey);
}
