Number properties
Number properties store quantitative values. Use plain Number for counts and scores, Currency when the value is money and needs a currency code attached, and Timer for durations. Numeric types are what reporting charts aggregate: sums, averages, and running totals all depend on the value being stored as a number rather than text. Choosing Currency over Number also formats the value correctly across the app and keeps the currency code with it.Number
A signed numeric value.
Currency
A monetary value with a currency code.
Timer
A duration in milliseconds.
