You can have a single type for “money” (or maybe just “us_money”) with separate cents/dollars/mills factories and accessors, and no access to a numeric value except through the accessors.

You can do similar things with other dimensions like “length”.

Or you can go whole hog, and have a single “type” for unit-aware values from which you can only successfully extract a unitless number by specifying a unit which is dimensionally compatible.

But most projects won’t do any of these because they will start out thinking they don’t need it, and by the time they realize the value they’ll think the cost of converting existing code is too high.
