Description
A Quantity represents anumeral value which has a display unit associated with it. For instance, the value "5" is described more specifically by a Quantity that also contains information about the unit of the value, e.g. "5 km/h".
Literal
The syntax for Literals for complex data types will be used, a QuantityLiteral is the code representation of a value of type NumericQuantity.
Value = LiteralCore Conversion
The following table shows the rules for conversion to another data type:
| Conversion | Result | Sample |
| ToBoolean | Undefined (should not be used) | |
| ToInteger | Returns the value of Quantity in integer value, float value will be truncated | Integer val = ToInteger(5.5 [@Unit, "BL_DataLibraMIB.odx", "km", 0]); // Returns 5 |
| ToFloat | Returns the value of Quantity in float value | Float val = ToFloat(5.5 [@Unit, "BL_DataLibraMIB.odx", "km", 0]); // Returns 5.5 |
| ToString | Returns the value of Quantity in string value | String s = ToString(5.5 [@Unit, "BL_DataLibraMIB.odx", "km", 0]); // Returns "5.5" |
| ToByteField | Undefined (should not be used) |
Sample
Quantities.Quantity QuantityVariable = 5 [@Unit, "BL_DataLibraMIB.odx", "km/h", 0];
