How do we assign 16 bytes unsigned Integer in PHP?

[mkwong8888]

We are unable to represent an unsigned integer with 16 bytes memory
size. The current integer size is 4 bytes by default. There is no way
for us to store large integer in this case.
The valid number range is from 0 to 2^128-1
(340282366920938463463374607431768211455).

Thank you.

floats can store numbers up to 1.8x10^308, that should be enough

Hi,

What is your question?

How to use big numbers?

Try searching for bc at www.php.net.
It is all there. :-)

Thank you.

But they don't have the precision he needs.

Look at the bcmath extension (http://www.php.net/manual/en/ref.bc.php). It
provides arbitrary precision number arithmetics. You can even specify how
many decimal numbers you want.

I saw these from an earlier post. try these. it will work to any precision
you want.
If your host won't allow you to include these libraries, write a precision
math class. I did once.
