Fixed-point. Simply put you keep monetary amounts in cents/pennies, not
Dollars/Pounds/Euros

The meaning of "legal obligation" varies with the legal province (a.k.a.
"country") you're in, and sometimes even with the particular profession.
E.g. shops are generally required to round to the nearest cent,
whereas banks may be obliged to compute down to 1 percent of a penny
(with "banker's rule" rounding to make it unbiased).

Because size_t can be equivalent to a different type, depending on the
platform and compiler settings.
