    1234.567 rounds down to 1234.56
    1234.123 rounds down to 1234.12
- precisioninteger, optional
  Represents the number of decimal places displayed for the currency value in the user interface. This value should be less than decimal_place
  Example: Currency value: $123.466, the precision value is set to 2, the final currency value will be $123.47. (Note: "rounding_option" : "round_up").
decimal_placeinteger, optional
Defines the maximum numberof decimal places allowed for storing currency values in the field. This value cannot exceed 9. Values exceeding the set decimal_place will be truncated during storage.

Notes

The precision value for currency should be less than the decimal_place.
The tooltip key supports only the info_icon value.
Maximum value for decimal_place is 9.
