What are the best practices for handling rounding and precision issues with floating-point numbers in PHP?

When working with floating-point numbers in PHP, it's important to be aware of rounding and precision issues that can arise due to the way computers represent and store these numbers. To handle these issues, you can use PHP's built-in functions like round(), number_format(), or sprintf() to control the precision of your calculations and format the output accordingly.

// Example: Rounding a floating-point number to 2 decimal places
$number = 10.45678;
$rounded_number = round($number, 2);
echo $rounded_number; // Output: 10.46
