PACK
The PACK function converts an integer to a text item that can be interpreted as a packed decimal number.
The sign values for packed data are as follows:
- C for positive (+)
- D for negative (-)
- F for unsigned, which is read as positive
- Syntax:
- PACK (single-integer-expression)
- Meaning:
- PACK (integer_to_conver)
- Returns:
- A single text item
In a packed decimal number, each half-byte is a digit, except for the last half-byte of the rightmost byte, which contains a sign.
Examples
- PACK (314)
Returns "1L" and results in the hex value 31 4C (which, in ASCII, looks like 1L)
- PACK ((Unit Price * Quantity) * 100)
In this example, the packed number has two implied decimal places. Because PACK does not accept decimal places, including implied ones, the nested arithmetic expression, Unit Price * Quantity, is multiplied by 100 before rounding.
Define items as having a packed decimal number presentation. Then, when mapping to or from these items, the conversion to and from packed decimal is automatically performed as needed.
