Are there any best practices for handling whole numbers and decimal numbers in PHP?

When handling both whole numbers and decimal numbers in PHP, it's important to be mindful of data types and precision. One common practice is to use the appropriate data type (int for whole numbers, float or double for decimal numbers) and to be cautious when performing arithmetic operations to avoid unexpected results due to floating-point precision issues.

// Example of handling whole numbers and decimal numbers in PHP

$wholeNumber = 10;
$decimalNumber = 3.14;

// Addition
$sum = $wholeNumber + $decimalNumber;
echo "Sum: " . $sum . "\n";

// Multiplication
$product = $wholeNumber * $decimalNumber;
echo "Product: " . $product . "\n";

// Division
$quotient = $wholeNumber / $decimalNumber;
echo "Quotient: " . $quotient . "\n";
