Value :: operator+ - Add two values

The operation provides the result of adding two values. The operation is an ordinary binary operation returning the result in the data format of the left operand (calling object). The operation behaves differently for different data types of the left operand:

1. Numbers (INT, REAL)

The operation builds the sum for the participating operands and returns the result with the data type of the first operand.

2. Text (STRING, CHAR, CCHAR)

The second operand is converted into text and appended to the text of the first operand.

3. Boolean (LOGICAL)

The second operand is converted into a Boolean value and the result is true, when one of the operands is true (or).

4. Date

The second operator is converted into an integer number and added as number of days to the date value in the first operand.

5. Time

The second operator is converted into an integer number and added as number of hundredth seconds to the date value in the first operand.

6. DateTime

The second operator is converted into an integer number and added as number of hundredth seconds to the timestamp value in the first operand.

7. Other

For all other data types for the left hand operand, the function throws an exception.
