How does casting a formatted number back to a float affect the formatting in PHP?

When casting a formatted number back to a float in PHP, the formatting is lost and the number is converted back to its original float value. To maintain the formatting, you can store the formatted number as a string and only cast it to a float when necessary for calculations. 

// Format a number as a string
$number = 1234.56;
$formattedNumber = number_format($number, 2);

// Store the formatted number as a string
$floatNumber = (float) $number; // Convert back to float when needed
