What alternative methods, such as BCMath, can be used to address precision issues in PHP calculations?

When dealing with precision issues in PHP calculations, one alternative method is to use the BCMath extension. BCMath allows for arbitrary precision arithmetic, which can help avoid common rounding errors that occur with floating point numbers in PHP. 

// Using BCMath to perform precise calculations
$number1 = '1.23456789';
$number2 = '9.87654321';

$sum = bcadd($number1, $number2, 10); // Add the two numbers with a precision of 10 decimal places

echo $sum; // Output: 11.11111110
