What are the potential pitfalls of rounding float values in PHP?

Rounding float values in PHP can lead to inaccuracies due to the way floating-point numbers are stored and manipulated internally. This can result in unexpected behavior and errors in calculations. To mitigate this issue, it is recommended to use the `number_format()` function to round float values to a specified number of decimal places while converting them to a string. 

$floatValue = 10.555;
$roundedValue = number_format($floatValue, 2);
echo $roundedValue; // Output: 10.56
