Type definition

IfcAppliedValueSelect defines a value to be calculated within a formula.

Types are used as follows:

IfcValue: A constant value using project default units.
IfcMeasureWithUnit: A constant value using specified units.
IfcReference: A value referenced on an object attribute.

For cost values, the following guidance applies:

IfcMeasureWithUnit allows the specification of both the actual figure for the value together with the currency in which the value is represented.
Selecting IfcMonetaryMeasure allows the specification only of the value, the currency being as set by the global context.
Selecting IfcRatioMeasure assumes that the amount is a percentage or other REAL number. Note that if the amount is normally specified as -20%, then this figure will need to be converted to a multiplier of 0.8
