Re: Re: Bad PHP error

Ok, I understand. But what can I do if I want to print big numbers like 123 billion? (but real numbers, not those written with the "E" letter in them? Is this possible with PHP or I need to do it with another language? Thank you. Teddy From: "M.

However, you shouldn't really see any difference in working, it's just treated as a double inside (a double float, that is).
