little problem with big numbers

nightwolfz

ok heres a (in short) how i made my lil code

$credits=intval($population*4);

lets say $credits result is 5000, everything works fine, but once the result is bigger then 2.1 bill it goes negative

How can I make so credits dont go negative when higher then 2.1 billion ? (I allready put BIGINT in mysql)

UNSIGNED BIGINT, however you're gonig to run into system limitations as well.

May I ask...why would you want to code with such large numbers anyway?!

ok i got anothe problem,

I need to store large numbers in a string without going negative

sample

 
$population=5000000000; // 500,000,000
$planets=68000000; // 680,000

$credits=intval(($population*14)+($planets*95));

echo "$credits";// result= -849411328

I know its caused because of intval(), i was wondering is there anything like bigintval() or anything simular?
