Re: Binary data types and some oddities

Y'all
I'm working on some conversion stuff and am looking at how binary numbers work on the iSeries. I've run across some curious things. 

Then I

SELECT HEX(BIN2P1) FROM BINTEST

and it displays 012F. Oops - that is a packed field with digits 12.

It is very likely that SQL does a hidden "CAST" when reading a binary field.
Then I DSPPFM BINTEST and press F10 & F11, to see the hex values. It shows 000C, which is 12 in decimal.
BTW, SQL does not have a binary type of this variety - it has only the INT variations. So there are no issues of decimal (binimal) points.
Weird? Of course, IBM have always said the in RPG a B and an I are not the same thing.
