How can PHP developers avoid common pitfalls when rounding numbers in their code?

When rounding numbers in PHP, developers should be aware of common pitfalls such as rounding errors due to floating-point precision. To avoid this, it is recommended to use PHP's built-in functions like round() or number_format() with the appropriate precision parameter. Additionally, developers should be cautious when comparing rounded numbers for equality due to potential discrepancies.

// Example of rounding a number with precision using round()
$number = 10.235;
$roundedNumber = round($number, 2);
echo $roundedNumber; // Output: 10.24
