What are some best practices for handling decimal numbers in PHP scripts, especially when using functions like rand()?

When working with decimal numbers in PHP scripts, especially when using functions like rand(), it's important to keep in mind that these functions typically generate whole numbers. To handle decimal numbers, you can multiply the result of rand() by a factor that represents the desired precision (e.g., 100 for two decimal places) and then divide by the same factor to get the decimal number.

// Generate a random decimal number between 0 and 1 with two decimal places
$randomDecimal = rand(0, 100) / 100;
echo $randomDecimal;
