Optional
decimalTells the display software how many
decimal places to move the decimal over to the left, or in other words,
which position corresponds to whole numbers. We require fungible digital
assets to be represented in integers, in the smallest unit (i.e. USD might
be represented in mill, a thousandth of a dollar. In that case,
decimalPlaces
would be 3.) This property is optional, and for
non-fungible digital assets, should not be specified. The decimalPlaces
property should be used for display purposes only. Any other use is an
anti-pattern.
