Using module 'complex' built from
http://webserver2.tecgraf.puc-rio.br/~lhf/ftp/lua/lcomplex.tar.gz
one finds
$ lua
Lua 5.3.3 Copyright (C) 1994-2016 Lua.org, PUC-Rio
> package.cpath = "./?.so"
> complex = require "complex"
> complex.version
complex number library for Lua 5.3 / Jun 2015
> complex.new()

This can be fixed in lcomplex.c as follows:
- if (x!=0) lua_pushnumber(L,x); */
+ if (x!=0 || y==0) lua_pushnumber(L,x);
