What are some potential pitfalls when using mathematical functions in PHP?

One potential pitfall when using mathematical functions in PHP is encountering division by zero errors. To avoid this, you can add a simple check to ensure that the denominator is not zero before performing the division. 

$numerator = 10;
$denominator = 0;

if ($denominator != 0) {
    $result = $numerator / $denominator;
    echo "Result: " . $result;
} else {
    echo "Error: Division by zero.";
}
