Which should i use then?

Try int64_t or uint64_t. You might need to do #include <inttypes.h>

This code is from the pre release protocol site (http://wiki.vg/Pre-release_protocol#Position)

Yeah the decoding is a mystery to me but maybe it's using shifting and overflow in order to mask bits...
I think in order to get z you simply do

Code:

z = val & 0x3FFFFFF;

But who knows, maybe what you wrote works if you use int64_t
