I think lua_pushinteger is simply not guaranteed to be exact.

(A hypothetical Lua variant with both floating point and arbitrary
precision integers could be interesting.  The trouble of doing that
with userdata is that you lose interoperability unless everybody uses
the same library for integers.)
