// 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
