> Property types for numeric and monetary values.

## Number properties

Number properties store quantitative values. Use plain
[Number](/data/properties/number/number) for counts and scores,
[Currency](/data/properties/number/currency) when the value is money and needs
a currency code attached, and [Timer](/data/properties/number/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.
