Are there any best practices for handling rounding of numbers in PHP?

When working with numbers in PHP, it is important to consider how rounding is handled to ensure accuracy in calculations. One common issue is the potential for rounding errors when working with floating-point numbers. To mitigate this, it is recommended to use PHP's built-in functions such as round(), ceil(), or floor() to round numbers to the desired precision.

// Example of rounding a number to 2 decimal places using round() function
$number = 10.56789;
$roundedNumber = round($number, 2);
echo $roundedNumber; // Output: 10.57
