Why does the `FILTER_VALIDATE_NUMBER_FLOAT` constant drop the decimal place character?

Question

$quantity = filter_input(INPUT_GET, 'quantity', FILTER_SANITIZE_NUMBER_FLOAT); 

Input: 100.25

Output: 10025

How can I preserve the . character?

Answer 1

Try this...

$quantity = filter_input(               INPUT_GET,                'quantity',                FILTER_SANITIZE_NUMBER_FLOAT,                FILTER_FLAG_ALLOW_FRACTION             );
