How can the inherent limitations of floating-point numbers in PHP impact script behavior?

Floating-point numbers in PHP have inherent limitations due to their precision. This can lead to rounding errors and inaccuracies in calculations, especially when dealing with very large or very small numbers. To mitigate this issue, it is recommended to use the BCMath extension in PHP, which provides arbitrary precision arithmetic functions for working with numbers with higher precision. 

// Example of using BCMath extension to perform calculations with higher precision
$number1 = '0.1';
$number2 = '0.2';

$sum = bcadd($number1, $number2, 10); // Specify precision as the third argument

echo $sum; // Output: 0.3
