What are some best practices for handling decimal values in PHP to avoid truncation or incorrect formatting?

When dealing with decimal values in PHP, it is important to use the correct data types and functions to avoid truncation or incorrect formatting. One common mistake is using the float data type, which can lead to precision issues. Instead, it is recommended to use the string data type or the BCMath extension for precise decimal calculations. 

// Using the BCMath extension for precise decimal calculations
$number1 = '1.23456789';
$number2 = '9.87654321';

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

echo $sum; // Output: 11.11111110
