%DEC Built-In Functions in rpgle

%DEC function can be used to convert Date, Time OR Timestamp to Decimal.

We use it in the form %DEC(date time or timestamp expression {:format}) The converted decimal value will have the number of digits like the date or time format that we mention here in 2nd parameter. e.g. if the 1st parameter is a Date and 2nd paramter is *YMD, the converted decimal value will be YYMMDD. Similarly for *MDY, the converted decimal will be MMDDYY.


Example 1–%dec built-in function in rpgle


%DEC(date time or timestamp expression {:format})

Here 2nd parameter is optional. In below example we are using only 1st paramter.
