What are the benefits of using bcmath for float precision in PHP calculations?

When performing calculations with floating-point numbers in PHP, precision issues can arise due to the way computers store these numbers. This can lead to inaccuracies in calculations, especially when dealing with financial or scientific data. The bcmath extension in PHP provides arbitrary precision arithmetic, allowing for more accurate calculations with floating-point numbers. 

// Using bcmath for float precision in PHP calculations
$number1 = '1.23456789';
$number2 = '9.87654321';

$sum = bcadd($number1, $number2, 8); // Adding the two numbers with 8 decimal places of precision

echo $sum; // Output: 11.11111110
