What are some common pitfalls to avoid when working with numerical operations in PHP?

One common pitfall when working with numerical operations in PHP is the issue of precision loss when performing calculations with floating-point numbers. To avoid this, it is recommended to use the BCMath extension in PHP, which provides arbitrary precision mathematics functions for working with numbers. 

// Example of using BCMath extension to perform precise numerical operations

$num1 = '1.23456789';
$num2 = '9.87654321';

$result = bcadd($num1, $num2, 8); // Add two numbers with 8 decimal places precision
echo $result; // Output: 11.11111110
