Description:
------------
This is fairly straightforward. Right now, native numeric types are float/doubles and 32-bit
integers.
Given that > 4GB of memory in a machine is affordable even for the home consumer, it is important
to be able to represent exact cardinal values without any floating-point nonsense.
I don't know how much impact this would have the internals of Zend, or performance for that
matter. Non-64-bit-native CPUs could probably adopt optimisations to avoid having to do 64-bit
operations on values / expressions where the values are not expected to exceed 32 bits of value, or
perhaps, via "type-hinting" by the programmer.
I realise that "bcmath" stuff can handle an effectively infinitely large integer value...
but that's really a string-math subsystem with all of the usual limitations (and performance
costs).
