/* In order to have a little more flexibility in integer precision vs efficiency,
we subdivide the integer types into three classes:
Small integers: Integers that never come close to overflowing their (machine word)
precision. We will always use int4 or uint4 (or smaller) for
these so that the precision is explicitly given.
Machine word integers: These integers exactly match the largest precision that
will fit in a general purpose register. They should be
used exclusively by in implementations of larger
precision objects. Use intm or uintm
/*
Big integers: These are intended to be arbitrary precison integers. However
for efficiency, these will always be implemented as fixed precision.
for efficiency, these are currently implemented as fixed precision.
So for coding purposes, these should be interpreted as fixed
precision integers that store as big a number as you would ever need.
