What are some potential pitfalls when using floating-point numbers in PHP, as highlighted in the forum thread?

One potential pitfall when using floating-point numbers in PHP is the issue of precision loss due to the way floating-point numbers are stored and manipulated internally. To mitigate this problem, it is recommended to use functions like number_format() or round() to control the precision of floating-point calculations.

$number = 10.1 + 0.2;
echo number_format($number, 1); // Output: 10.3
