QuantityVariable = QuantityTerm * NumericTerm;

This is a term which returns as a result of the product of all numerical quantities (NumericQuantity) in accordance with their units.

When Quantity values are multiplied, a definition of the physical dimension of the resulting Quantity has to exist in the UNIT-SPEC available to the OTX system.

Scalar operands will be interpreted "as is"; this allows e.g. the multiplication of 2 * 2 km which will result in a Quantity of 4000 m.

The display unit of the resulting Quantity will be set to the SI base unit corresponding to the physical dimension resulting from the operation. Furthermore, the display precision of the resulting Quantity will be the maximum of the display precisions of the operands.

The Term returns the value, see table below.

In OTX, Terms are categorized according to its return data type!

Data Type	Description
Quantity	Product of two or more numeric quantity (NumericQuantity)

Name	Data Type	Class	Default	Cardinality	Description
QuantityTerm	Quantity	Term	-	[1..*]	Quantity values are multiplied
NumericTerm	Numeric	Term	-	[0..*]	Numeric values are multiplied
