What are the potential pitfalls of using PEAR Math Finance implementation in PHP for financial calculations, and how can they be avoided?

One potential pitfall of using PEAR Math Finance implementation in PHP for financial calculations is the lack of support and updates, which can lead to outdated or incorrect results. To avoid this, it is recommended to regularly check for updates and consider using more actively maintained libraries or custom implementations.

// Check for updates and consider using more actively maintained libraries
// Alternatively, create custom implementations for financial calculations

// Example of custom implementation for calculating compound interest
function calculateCompoundInterest($principal, $rate, $time) {
    $compoundInterest = $principal * (pow((1 + $rate), $time) - 1);
    return $compoundInterest;
}
