> For the integer thing, it's more the problem that when waiting for IO, due to the speeds and amounts of data, it becomes a double upon dividing, if divided correctly. But it the system time has to be an integer, then I'd have to consistently round up. Which means I wouldn't have to use doubles. My approach doesn't move through time by one microsecond at each point, and instead just skips to the next time. This is why this is more of a problem.
