-// important properties of PHP's integers:
-// - always signed (one bit short of PHP_INT_SIZE)
-// - conversion from string to int is saturated
-// - float is double
-// - div converts arguments to floats
-// - mod converts arguments to ints
-
-// the packing code below works as follows:
-// - when we got an int, just pack it
-// if performance is a problem, this is the branch users should aim for
-//
-// - otherwise, we got a number in string form
-// this might be due to different reasons, but we assume that this is
-// because it didn't fit into PHP int
-//
-// - factor the string into high and low ints for packing
-// - if we have bcmath, then it is used
-// - if we don't, we have to do it manually (this is the fun part)
-//
-// - x64 branch does factoring using ints
-// - x32 (ab)uses floats, since we can't fit unsigned 32-bit number into an int
-//
-// unpacking routines are pretty much the same.
-// - return ints if we can
-// - otherwise format number into a string
