You are right.
This is how I ended up solving it (note the LUA_NUMBER_INTEGER define):
case 'd': case 'i': {
lua_Number n = luaL_checknumber(L, arg);
#ifndef LUA_NUMBER_INTEGER
luaL_argcheck(L, (MIN_INTFRM - 1) < n && n < (MAX_INTFRM + 1), arg,
"not a number in proper range");
#endif
addlenmod(form, LUA_INTFRMLEN);
nb = sprintf(buff, form, (LUA_INTFRM_T)n);
break;
}
case 'o': case 'u': case 'x': case 'X': {
lua_Number n = luaL_checknumber(L, arg);
#ifndef LUA_NUMBER_INTEGER
luaL_argcheck(L, 0 <= n && n < (MAX_UINTFRM + 1), arg,
"not a non-negative number in proper range");
#endif
addlenmod(form, LUA_INTFRMLEN);
nb = sprintf(buff, form, (unsigned LUA_INTFRM_T)n);
break;
}
