What is the difference between using integers and float values in PHP for calculations?

When performing calculations in PHP, it is important to understand the difference between integers and float values. Integers are whole numbers without decimal points, while float values are numbers with decimal points. When using integers in calculations, the result will also be an integer, potentially leading to loss of precision for division operations. To ensure accurate calculations, it is recommended to use float values when dealing with numbers that require decimal points. 

// Using float values for calculations
$num1 = 10.5;
$num2 = 3.5;

$result = $num1 + $num2;
echo $result; // Output: 14
