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 should 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 should be truncat | Integer val = ToInteger(@Quantity:5.5/"km"); // Returns 5 |
| ToFloat | Returns the value of Quantity in float value | Float val = ToFloat(@Quantity:5.5/"km"); // Returns 5.5 |
| ToString | Returns the value of Quantity in string value | String s = ToString(@Quantity:5.5/"km"); // Returns "5.5" |
| ToByteField | Undefined (should not be used) |
Sample
Quantity MyQuantityVariable = @Quantity:5/"km";
