Keep a huge material count honest when tiny crafts keep adding to it

After a few hours an idle game counts materials in the trillions, and suddenly a craft that should cost exactly what you have says you are short, or the stock does not move at all. Ordinary numbers drift. This entry shows a small number type that compares fairly and settles tiny leftovers.

Why this works

Computers keep only so many digits, so a huge number swallows a small one and tiny errors pile up. Storing a number as a size and a digit part, comparing with a little give and cleaning up crumbs, keeps what the player sees in line with what is really owned.

When not to use it

Skip this in a game whose numbers stay modest, say below a few billion. Ordinary numbers are exact enough there, and the extra care only slows things down and makes saves harder to read.
