            Must be a number between 0 and 10, as the Daml interfaces represent
            holding amounts as

            `Decimal` values, which use 10 decimal places and are precise for 38
            digits.

            Setting this to 0 means that the instrument can only be held in
            whole units.


            This number SHOULD be used for display purposes in a wallet to
            decide how many

            decimal places to show and accept when displaying or entering
            amounts.
