OTL Syntax
QuantityVariable = QuantityTerm + NumericTerm;
Description
This is a term which, as a result the sum of all numerical quantities (NumericQuantity returns) with respect to their units.
- When Quantity values are added, the physical dimensions of the display unit of all Quantity operands shall be identical.
- If scalar operands exist, they shall be interpreted as normalized values according to the physical dimension of the Quantity operands. This allows e.g. the addition of 2 km + 1 m + 11 which will result in a Quantity of 2012 m.
- The display unit of the resulting Quantity should be set to the SI base unit corresponding to the Quantity's physical dimension. Furthermore, the display precision of the resulting Quantity shall be the maximum of the display precisions of the operands.
Return Value
