Cash

A territory's cash-rounding practice for its tender: the currency the row governs, the increment in 10^-digits units of that currency, the midpoint mode, and - separately, because the two genuinely differ in kind - where each of those facts comes from.

Keyed by territory because the practice is the jurisdiction's. Switzerland's increment follows from its denomination set with no rounding provision in any instrument; Denmark's is statutory while its midpoint is stated by nothing; Finland's statute states both. Unstated marks a value no source states, recorded as this library's own documented choice rather than attributed to a rule that does not exist. Instances via Cash.
