Class DV_AMOUNT

Abstract class defining the concept of relative quantified amounts'. For relative quantities,
the +' and -' operators are defined (unlike descendants of DV_ABSOLUTE_QUANTITY,
such as the date/time types).

Attribut accuracy

Accuracy of measurement, expressed either
as a half-range percent value
(accuracy_is_percent = True) or a half-range
quantity. A value of 0 means that accuracy
was not recorded.

Declaration :

Uml : + accuracy : Real, multiplicity : 0..1
C++ : public: double accuracy
Java : public double accuracy

Attribut accuracy_is_percent

If True, indicates that when this object was
created, accuracy was recorded as a percent
value

Declaration :

Uml : + accuracy_is_percent : Boolean, multiplicity : 0..1
C++ : public: bool accuracy_is_percent
Java : public boolean accuracy_is_percent

Operation valid_percentage

Test whether a number is a valid percentage,
i.e. between 0 and 100.

Declaration :

Uml : + valid_percentage(in number : magnitude) : Boolean
C++ : public: bool valid_percentage()
Java : public boolean valid_percentage()

Operation operator=

Declaration :

Uml : + operator=(in source : DV_AMOUNT) : DV_AMOUNT
C++ : public: DV_AMOUNT & operator=(const DV_AMOUNT & source)

Operation operator+

Sum of this quantity and another whose formal type must be the
difference type of this quantity.

Declaration :

Uml : + operator+(in other : DV_AMOUNT) : DV_AMOUNT
C++ : public: DV_AMOUNT & operator+(const DV_AMOUNT & other) const

Operation operator-

Negated version of current object, such as used for representing a
difference, e.g. a weight loss.

Declaration :

Uml : + operator-(in other : DV_AMOUNT) : DV_AMOUNT
C++ : public: DV_AMOUNT & operator-(const DV_AMOUNT & other)
