Using luaL_tolstring will change the type of number values to string.
I use this:
static void dumpstack (lua_State *L, const char *message) {
int top=lua_gettop(L);
int i;
printf("dumpstack -- %s\n",message);
for (i=1; i<=top; i++) {
printf("%d\t%s\t",i,luaL_typename(L,i));
switch (lua_type(L, i)) {
case LUA_TNUMBER:
printf("%g\n",lua_tonumber(L,i));
break;
case LUA_TSTRING:
printf("%s\n",lua_tostring(L,i));
break;
case LUA_TBOOLEAN:
printf("%s\n", (lua_toboolean(L, i) ? "true" : "false"));
break;
case LUA_TNIL:
printf("%s\n", "nil");
break;
default:
printf("%p\n",lua_topointer(L,i));
break;
}
}
printf("dumpstack -- END\n");
}
