calculate with numbers larger than any datatype can hold

Hi there.

I am writing an application that will calculate with numbers larger than any standard datatype php has can handle.

What can I do?

thanks.

 

This might help
http://en.wikipedia.org/wiki/Arbitrary-precision_arithmetic

 

Also take a look at these two PHP libraries
http://www.php.net/manual/en/book.gmp.php
http://www.php.net/manual/en/book.bc.php

 

maybe try Math_BigInteger pear.php.net/package/Math_BigInteger

and it's corresponding site:phpseclib.sourceforge.net/documentation/math.html
