0x03 Formatting attribute set
The following set of attributes provides the ratios and formatting hints required to transform the received
summations, consumptions or demands/rates into displayable values. If the Multiplier and Divisor attribute values
are non-zero, they are used in conjunction with the
SummationFormatting, ConsumptionFormatting
, and
DemandFormatting
attributes. Equations required to accomplish this task are defined below:
Summation = Summation received * Multiplier / Divisor
(formatted using
SummationFormatting
)
Consumption = Summation received * Multiplier / Divisor
(formatted using
ConsumptionFormatting
)
Demand = Demand received * Multiplier / Divisor
(formatted using
DemandFormatting
)
