Subject: Allow infinity integer length
From: david.proweb@gmail.com (David Rodrigues)

Currently PHP integer is limited to 2147483647 or 9223372036854775807
(PHP_INT_MAX), depending of system bits. We can works with long
integers by using bcmath, for instance. But why not to support it
natively?

I mean, PHP can parse infinity integers, but it's converted to
cientific notation or to INF.

My suggestion is that, instead of convert it, stores the value in
another format, an int[] or string, expanding depending of parsed
length.

Then accept things like:

10000000000000000000000000000000 + 10000000000000000000000000000000 =
20000000000000000000000000000000

Yeah, I know that it should be slower than normal ints, but is an
exceptional case. It should avoid problems caused by untested code
with very large numbers, for instance.

Same for float values, but in this case I think that should have a
best implementation to defines length of mantissa, for instance (new
Float($float, $bits), for instance). But it can be part of another
discussion.
